CVE-2022-22721 – core: Possible buffer overflow with very large or unlimited LimitXMLRequestBody
https://notcve.org/view.php?id=CVE-2022-22721
If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier. Si LimitXMLRequestBody está configurado para permitir cuerpos de petición de más de 350 MB (por defecto 1M) en sistemas de 32 bits, es producido un desbordamiento de enteros que causa posteriormente escrituras fuera de límites. Este problema afecta a Apache HTTP Server 2.4.52 y anteriores A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option.

CVE-2022-21716 – Buffer Overflow in Twisted
https://notcve.org/view.php?id=CVE-2022-21716
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. • https://github.com/twisted/twisted/commit/89c395ee794e85a9657b112c4351417850330ef9 https://github.com/twisted/twisted/releases/tag/twisted-22.2.0 https://github.com/twisted/twisted/security/advisories/GHSA-rv6r-3f5q-9rgx https://lists.debian.org/debian-lts-announce/2022/03/msg00009.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7U6KYDTOLPICAVSR34G2WRYLFBD2YW5K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GLKHA6WREIVAMBQD7KKWYHPHGGNKMAG6 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-770: Allocation of Resources Without Limits or Throttling •
