An issue was discovered in the CheckUser extension for MediaWiki through 1.39.3. When a user with checkuserlog permissions makes many CheckUserLog API requests in some configurations, denial of service can occur (RequestTimeoutException or upstream request timeout).

Ubuntu Security Notice 5991-1 - It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service. It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5990-1 - It was discovered that musl did not handle certain i386 math functions properly. An attacker could use this vulnerability to cause a denial of service or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, and Ubuntu 18.04 LTS. It was discovered that musl did not handle wide-character conversion properly. A remote attacker could use this vulnerability to cause resource consumption , denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.

Ubuntu Security Notice 5989-1 - Tao Lyu discovered that GlusterFS did not properly handle certain event notifications. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 5988-1 - It was discovered that integer overflows vulnerabilities existed in Xcftools. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

Qubes Mirage Firewall versions 0.8.0 through 0.8.3 suffer from a denial of service vulnerability.

Plus: Microsoft Outlook and Android patch serious flaws, Chrome and Firefox get fixes, and much more.

A ReDoS issue was discovered in the Time component through 0.2.1 in Ruby through 3.2.1. The Time parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to Time objects. The fixed versions are 0.1.1 and 0.2.2.

There is a possible Denial of Service (DoS) vulnerability in the unpoly-rails gem that implements the [Unpoly server protocol](https://unpoly.com/up.protocol) for Rails applications. ### Impact This issues affects Rails applications that operate as an upstream of a load balancer's that uses [passive health checks](https://docs.nginx.com/nginx/admin-guide/load-balancer/http-health-check/#passive-health-checks). The [unpoly-rails](https://github.com/unpoly/unpoly-rails/) gem echoes the request URL as an `X-Up-Location` response header. By making a request with exceedingly long URLs (paths or query string), an attacker can cause unpoly-rails to write a exceedingly large response header. If the response header is too large to be parsed by a load balancer downstream of the Rails application, it may cause the load balancer to remove the upstream from a load balancing group. This causes that application instance to become unavailable until a configured timeout is reached or until an activ...

### Impact In certain configurations, data sent by remote servers containing special strings in key locations could cause modifications of the `Object.prototype`, disrupting matrix-js-sdk functionality, causing denial of service and potentially affecting program logic. (This is part 2, where [CVE-2022-36059](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-36059) / [GHSA-rfv9-x7hh-xc32](https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-rfv9-x7hh-xc32) is part 1. Part 2 covers remaining vectors not covered by part 1, found in a codebase audit scheduled after part 1.) ### Patches The issue has been patched in matrix-js-sdk 24.0.0. ### Workarounds None. ### References - [Release blog post](https://matrix.org/blog/2023/03/28/security-releases-matrix-js-sdk-24-0-0-and-matrix-react-sdk-3-69-0) - The advisory [GHSA-rfv9-x7hh-xc32](https://github.com/matrix-org/matrix-js-sdk/security/advisories/GHSA-rfv9-x7hh-xc32) ([CVE-2022-36059](https://cve.mitre.org/cgi-bin...
