| CVE-2021-29471 | 2 Fedoraproject, Matrix | 2 Fedora, Synapse | 2024-11-21 | 3.7 Low |
| Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.33.2 "Push rules" can specify conditions under which they will match, including `event_match`, which matches event content against a pattern including wildcards. Certain patterns can cause very poor performance in the matching engine, leading to a denial-of-service when processing moderate length events. The issue is patched in version 1.33.2. A potential workaround might be to prevent users from making custom push rules, by blocking such requests at a reverse-proxy. | ||||
| CVE-2021-29469 | 1 Redis.js | 1 Redis | 2024-11-21 | 5.3 Medium |
| Node-redis is a Node.js Redis client. Before version 3.1.1, when a client is in monitoring mode, the regex begin used to detected monitor messages could cause exponential backtracking on some strings. This issue could lead to a denial of service. The issue is patched in version 3.1.1. | ||||
| CVE-2021-29453 | 1 Matrix-media-repo Project | 1 Matrix-media-repo | 2024-11-21 | 5.7 Medium |
| matrix-media-repo is an open-source multi-domain media repository for Matrix. Versions 1.2.6 and earlier of matrix-media-repo do not properly handle malicious images which are crafted to be small in file size, but large in complexity. A malicious user could upload a relatively small image in terms of file size, using particular image formats, which expands to have extremely large dimensions during the process of thumbnailing. The server can be exhausted of memory in the process of trying to load the whole image into memory for thumbnailing, leading to denial of service. Version 1.2.7 has a fix for the vulnerability. | ||||
| CVE-2021-29433 | 1 Matrix | 1 Sydent | 2024-11-21 | 4.3 Medium |
| Sydent is a reference Matrix identity server. In Sydent versions 2.2.0 and prior, sissing input validation of some parameters on the endpoints used to confirm third-party identifiers could cause excessive use of disk space and memory leading to resource exhaustion. A patch for the vulnerability is in version 2.3.0. No workarounds are known to exist. | ||||
| CVE-2021-29430 | 1 Matrix | 1 Sydent | 2024-11-21 | 7.5 High |
| Sydent is a reference Matrix identity server. Sydent does not limit the size of requests it receives from HTTP clients. A malicious user could send an HTTP request with a very large body, leading to memory exhaustion and denial of service. Sydent also does not limit response size for requests it makes to remote Matrix homeservers. A malicious homeserver could return a very large response, again leading to memory exhaustion and denial of service. This affects any server which accepts registration requests from untrusted clients. This issue has been patched by releases 89071a1, 0523511, f56eee3. As a workaround request sizes can be limited in an HTTP reverse-proxy. There are no known workarounds for the problem with overlarge responses. | ||||
| CVE-2021-29060 | 1 Color-string Project | 1 Color-string | 2024-11-21 | 5.3 Medium |
| A Regular Expression Denial of Service (ReDOS) vulnerability was discovered in Color-String version 1.5.5 and below which occurs when the application is provided and checks a crafted invalid HWB string. | ||||
| CVE-2021-29059 | 2 Is-svg Project, Redhat | 2 Is-svg, Openshift | 2024-11-21 | 7.5 High |
| A vulnerability was discovered in IS-SVG version 2.1.0 to 4.2.2 and below where a Regular Expression Denial of Service (ReDOS) occurs if the application is provided and checks a crafted invalid SVG string. | ||||
| CVE-2021-29057 | 1 Thoughtworks | 1 Node-worker-threads-pool | 2024-11-21 | 6.5 Medium |
| An issue was discovered in StaticPool in SUCHMOKUO node-worker-threads-pool version 1.4.3, allows attackers to cause a denial of service. | ||||
| CVE-2021-28713 | 2 Debian, Xen | 2 Debian Linux, Xen | 2024-11-21 | 6.5 Medium |
| Rogue backends can cause DoS of guests via high frequency events T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen offers the ability to run PV backends in regular unprivileged guests, typically referred to as "driver domains". Running PV backends in driver domains has one primary security advantage: if a driver domain gets compromised, it doesn't have the privileges to take over the system. However, a malicious driver domain could try to attack other guests via sending events at a high frequency leading to a Denial of Service in the guest due to trying to service interrupts for elongated amounts of time. There are three affected backends: * blkfront patch 1, CVE-2021-28711 * netfront patch 2, CVE-2021-28712 * hvc_xen (console) patch 3, CVE-2021-28713 | ||||

| CVE-2021-28651 | 5 Debian, Fedoraproject, Netapp and 2 more | 5 Debian Linux, Fedora, Cloud Manager and 2 more | 2024-11-21 | 7.5 High |
| An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption. | ||||
| CVE-2021-28148 | 1 Grafana | 1 Grafana | 2024-11-21 | 7.5 High |
| One of the usage insights HTTP API endpoints in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5 is accessible without any authentication. This allows any unauthenticated user to send an unlimited number of requests to the endpoint, leading to a denial of service (DoS) attack against a Grafana Enterprise instance. | ||||
| CVE-2021-28092 | 2 Is-svg Project, Redhat | 3 Is-svg, Acm, Openshift | 2024-11-21 | 7.5 High |

| CVE-2021-27292 | 2 Redhat, Ua-parser-js Project | 5 Acm, Jaeger, Logging and 2 more | 2024-11-21 | 7.5 High |
| ua-parser-js >= 0.7.14, fixed in 0.7.24, uses a regular expression which is vulnerable to denial of service. If an attacker sends a malicious User-Agent header, ua-parser-js will get stuck processing it for an extended period of time. | ||||
| CVE-2021-27291 | 4 Debian, Fedoraproject, Pygments and 1 more | 6 Debian Linux, Fedora, Pygments and 3 more | 2024-11-21 | 7.5 High |
| In pygments 1.1+, fixed in 2.7.4, the lexers used to parse programming languages rely heavily on regular expressions.
