CVE-2025-3576 | 1 Redhat | 3 Ansible Automation Platform, Enterprise Linux, Openshift | 2025-06-06 | 5.9 Medium |
A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This may lead to unauthorized message tampering. | ||||
CVE-2024-3056 | 3 Fedoraproject, Podman Project, Redhat | 5 Fedora, Podman, Enterprise Linux and 2 more | 2025-06-03 | 7.7 High |
A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system. | ||||
CVE-2024-7079 | 1 Redhat | 2 Openshift, Openshift Container Platform | 2025-06-03 | 6.5 Medium |
A flaw was found in the Openshift console. The /API/helm/verify endpoint is tasked to fetch and verify the installation of a Helm chart from a URI that is remote HTTP/HTTPS or local. Access to this endpoint is gated by the authHandlerWithUser() middleware function. Contrary to its name, this middleware function does not verify the validity of the user's credentials. As a result, unauthenticated users can access this endpoint. | ||||
CVE-2024-7409 | 1 Redhat | 4 Advanced Virtualization, Enterprise Linux, Openshift and 1 more | 2025-06-03 | N/A |
A flaw was found in the QEMU NBD Server. This vulnerability allows a denial of service (DoS) attack via improper synchronization during socket closure when a client keeps a socket open as the server is taken offline. | ||||
CVE-2024-6119 | 3 Netapp, Openssl, Redhat | 34 500f, 500f Firmware, A250 and 31 more | 2025-06-03 | 7.5 High |
Issue summary: Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address resulting in abnormal termination of the application process. Impact summary: Abnormal termination of an application can a cause a denial of service. Applications performing certificate name checks (e.g., TLS clients checking server certificates) may attempt to read an invalid memory address when comparing the expected name with an `otherName` subject alternative name of an X.509 certificate. This may result in an exception that terminates the application program. Note that basic certificate chain validation (signatures, dates, ...) is not affected, the denial of service can occur only when the application also specifies an expected DNS name, Email address or IP address. TLS servers rarely solicit client certificates, and even when they do, they generally don't perform a name check against a reference identifier (expected identity), but rather extract the presented identity after checking the certificate chain. So TLS servers are generally not affected and the severity of the issue is Moderate. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. | ||||
CVE-2024-52615 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-06-02 | 5.3 Medium |
A flaw was found in Avahi-daemon, which relies on fixed source ports for wide-area DNS queries. This issue simplifies attacks where malicious DNS responses are injected. | ||||
CVE-2025-26465 | 4 Debian, Netapp, Openbsd and 1 more | 9 Debian Linux, Active Iq Unified Manager, Ontap and 6 more | 2025-06-02 | 6.8 Medium |
A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning the attack complexity high. | ||||
CVE-2024-8176 | 1 Redhat | 9 Devworkspace, Discovery, Enterprise Linux and 6 more | 2025-06-02 | 7.5 High |
A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the environment and library usage. | ||||
CVE-2024-12243 | 1 Redhat | 4 Discovery, Enterprise Linux, Openshift and 1 more | 2025-06-02 | 5.3 Medium |
A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition. | ||||
CVE-2024-12133 | 1 Redhat | 4 Discovery, Enterprise Linux, Openshift and 1 more | 2025-06-02 | 5.3 Medium |
A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. | ||||
CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-06-02 | 7.5 High |
A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
CVE-2024-2905 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Eus | 2025-05-29 | 6.2 Medium |
A security vulnerability has been discovered within rpm-ostree, pertaining to the /etc/shadow file in default builds having the world-readable bit enabled. This issue arises from the default permissions being set at a higher level than recommended, potentially exposing sensitive authentication data to unauthorized access. | ||||
CVE-2022-2995 | 2 Kubernetes, Redhat | 2 Cri-o, Openshift | 2025-05-29 | 7.1 High |
Incorrect handling of the supplementary groups in the CRI-O container engine might lead to sensitive information disclosure or possible data modification if an attacker has direct access to the affected container where supplementary groups are used to set access permissions and is able to execute a binary code in that container. | ||||
CVE-2025-1118 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 4.4 Medium |
A flaw was found in grub2. Grub's dump command is not blocked when grub is in lockdown mode, which allows the user to read any memory information, and an attacker may leverage this in order to extract signatures, salts, and other sensitive information from the memory. | ||||
CVE-2025-0677 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 6.4 Medium |
A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grub_malloc() may be called with a smaller value than needed. When further reading the data from the disk into the buffer, the grub_ufs_lookup_symlink() function will write past the end of the allocated size. An attack can leverage this by crafting a malicious filesystem, and as a result, it will corrupt data stored in the heap, allowing for arbitrary code execution used to by-pass secure boot mechanisms. | ||||
CVE-2025-0622 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-29 | 6.4 Medium |
A flaw was found in command/gpg. In some scenarios, hooks created by loaded modules are not removed when the related module is unloaded. This flaw allows an attacker to force grub2 to call the hooks once the module that registered it was unloaded, leading to a use-after-free vulnerability. If correctly exploited, this vulnerability may result in arbitrary code execution, eventually allowing the attacker to bypass secure boot protections. | ||||
CVE-2025-26466 | 4 Canonical, Debian, Openbsd and 1 more | 5 Ubuntu Linux, Debian Linux, Openssh and 2 more | 2025-05-27 | 5.9 Medium |
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack. | ||||
CVE-2025-4382 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-26 | 5.9 Medium |
A flaw was found in systems utilizing LUKS-encrypted disks with GRUB configured for TPM-based auto-decryption. When GRUB is set to automatically decrypt disks using keys stored in the TPM, it reads the decryption key into system memory. If an attacker with physical access can corrupt the underlying filesystem superblock, GRUB will fail to locate a valid filesystem and enter rescue mode. At this point, the disk is already decrypted, and the decryption key remains loaded in system memory. This scenario may allow an attacker with physical access to access the unencrypted data without any further authentication, thereby compromising data confidentiality. Furthermore, the ability to force this state through filesystem corruption also presents a data integrity concern. | ||||
CVE-2024-45776 | 1 Redhat | 2 Enterprise Linux, Openshift | 2025-05-26 | 6.7 Medium |
When reading the language .mo file in grub_mofile_open(), grub2 fails to verify an integer overflow when allocating its internal buffer. A crafted .mo file may lead the buffer size calculation to overflow, leading to out-of-bound reads and writes. This flaw allows an attacker to leak sensitive data or overwrite critical data, possibly circumventing secure boot protections. | ||||
CVE-2021-43859 | 6 Debian, Fedoraproject, Jenkins and 3 more | 14 Debian Linux, Fedora, Jenkins and 11 more | 2025-05-23 | 7.5 High |
XStream is an open source java library to serialize objects to XML and back again. Versions prior to 1.4.19 may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. XStream 1.4.19 monitors and accumulates the time it takes to add elements to collections and throws an exception if a set threshold is exceeded. Users are advised to upgrade as soon as possible. Users unable to upgrade may set the NO_REFERENCE mode to prevent recursion. See GHSA-rmr5-cpv2-vgjf for further details on a workaround if an upgrade is not possible. |
