| The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

| CVE-2025-27516 | 1 Redhat | 9 Ansible Automation Platform, Enterprise Linux, Openshift and 6 more | 2025-05-01 | 7.3 High |
| Jinja is an extensible templating engine. Prior to 3.1.6, an oversight in how the Jinja sandboxed environment interacts with the |attr filter allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends on the type of application using Jinja. This vulnerability impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to str.format and ensures they don't escape the sandbox. However, it's possible to use the |attr filter to get a reference to a string's plain format method, bypassing the sandbox. After the fix, the |attr filter no longer bypasses the environment's attribute lookup. This vulnerability is fixed in 3.1.6. | ||||
| CVE-2024-3727 | 1 Redhat | 18 Acm, Advanced Cluster Security, Ansible Automation Platform and 15 more | 2025-04-29 | 8.3 High |
| A flaw was found in the github.com/containers/image library. This flaw allows attackers to trigger unexpected authenticated registry accesses on behalf of a victim user, causing resource exhaustion, local path traversal, and other attacks. | ||||
| CVE-2020-35498 | 4 Debian, Fedoraproject, Openvswitch and 1 more | 5 Debian Linux, Fedora, Openvswitch and 2 more | 2025-04-23 | 7.5 High |
| A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2022-21712 | 4 Debian, Fedoraproject, Redhat and 1 more | 4 Debian Linux, Fedora, Openstack and 1 more | 2025-04-23 | 7.5 High |
| twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds. | ||||
| CVE-2022-21698 | 4 Fedoraproject, Prometheus, Rdo Project and 1 more | 17 Extra Packages For Enterprise Linux, Fedora, Client Golang and 14 more | 2025-04-23 | 7.5 High |
| client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods. | ||||
| CVE-2022-24761 | 3 Agendaless, Debian, Redhat | 3 Waitress, Debian Linux, Openstack | 2025-04-23 | 7.5 High |
| Waitress is a Web Server Gateway Interface server for Python 2 and 3. When using Waitress versions 2.1.0 and prior behind a proxy that does not properly validate the incoming HTTP request matches the RFC7230 standard, Waitress and the frontend proxy may disagree on where one request starts and where it ends. This would allow requests to be smuggled via the front-end proxy to waitress and later behavior. There are two classes of vulnerability that may lead to request smuggling that are addressed by this advisory: The use of Python's `int()` to parse strings into integers, leading to `+10` to be parsed as `10`, or `0x01` to be parsed as `1`, where as the standard specifies that the string should contain only digits or hex digits; and Waitress does not support chunk extensions, however it was discarding them without validating that they did not contain illegal characters. This vulnerability has been patched in Waitress 2.1.1. A workaround is available. When deploying a proxy in front of waitress, turning on any and all functionality to make sure that the request matches the RFC7230 standard. Certain proxy servers may not have this functionality though and users are encouraged to upgrade to the latest version of waitress instead. | ||||
| CVE-2022-24801 | 5 Debian, Fedoraproject, Oracle and 2 more | 6 Debian Linux, Fedora, Zfs Storage Appliance Kit and 3 more | 2025-04-23 | 8.1 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy. | ||||
| CVE-2022-31117 | 3 Fedoraproject, Redhat, Ultrajson Project | 3 Fedora, Openstack, Ultrajson | 2025-04-23 | 5.9 Medium |
| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON 5.4.0. There are no known workarounds for this issue. | ||||
| CVE-2022-21716 | 5 Debian, Fedoraproject, Oracle and 2 more | 6 Debian Linux, Fedora, Http Server and 3 more | 2025-04-22 | 7.5 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds. | ||||
| CVE-2022-31116 | 3 Fedoraproject, Redhat, Ultrajson Project | 3 Fedora, Openstack, Ultrajson | 2025-04-22 | 7.5 High |
| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Affected versions were found to improperly decode certain characters. JSON strings that contain escaped surrogate characters not part of a proper surrogate pair were decoded incorrectly. Besides corrupting strings, this allowed for potential key confusion and value overwriting in dictionaries. All users parsing JSON from untrusted sources are vulnerable. From version 5.4.0, UltraJSON decodes lone surrogates in the same way as the standard library's `json` module does, preserving them in the parsed output. Users are advised to upgrade. There are no known workarounds for this issue. | ||||
| CVE-2021-22570 | 6 Debian, Fedoraproject, Google and 3 more | 11 Debian Linux, Fedora, Protobuf and 8 more | 2025-04-21 | 6.5 Medium |
| Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater. | ||||
| CVE-2017-13673 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack | 2025-04-20 | N/A |
| The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function. | ||||
| CVE-2017-12440 | 2 Openstack, Redhat | 2 Openstack, Openstack | 2025-04-20 | N/A |
| Aodh as packaged in Openstack Ocata and Newton before change-ID I8fd11a7f9fe3c0ea5f9843a89686ac06713b7851 and before Pike-rc1 does not verify that trust IDs belong to the user when creating alarm action with the scheme trust+http, which allows remote authenticated users with knowledge of trust IDs where Aodh is the trustee to obtain a Keystone token and perform unspecified authenticated actions by adding an alarm action with the scheme trust+http, and providing a trust id where Aodh is the trustee. | ||||
| CVE-2017-13711 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 7.5 High |
| Use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU (aka Quick Emulator) allows attackers to cause a denial of service (QEMU instance crash) by leveraging failure to properly clear ifq_so from pending packets. | ||||
| CVE-2017-10906 | 2 Fluentd, Redhat | 3 Fluentd, Openstack, Openstack-optools | 2025-04-20 | N/A |
| Escape sequence injection vulnerability in Fluentd versions 0.12.29 through 0.12.40 may allow an attacker to change the terminal UI or execute arbitrary commands on the device via unspecified vectors. | ||||
| CVE-2017-10664 | 3 Debian, Qemu, Redhat | 11 Debian Linux, Qemu, Enterprise Linux and 8 more | 2025-04-20 | 7.5 High |
| qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. | ||||
| CVE-2017-12155 | 2 Ceph, Redhat | 2 Ceph, Openstack | 2025-04-20 | N/A |
| A resource-permission flaw was found in the openstack-tripleo-heat-templates package where ceph.client.openstack.keyring is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume. | ||||
| CVE-2017-14167 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 8.8 High |
