A flaw was found in Libevent, an event notification library. A remote attacker could exploit an out-of-bounds read vulnerability in the decodetaginternal function by sending specially crafted, attacker-controlled tagged RPC Remote Procedure Call data.

Important: libevent

Issue Overview: Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent can read beyond a contiguous evbuffer region in eventtagging.c when decodetaginternal requests at most five bytes from evbufferpullup but iterates using the full logical buffer length. A fragmente...

Alexis Challande discovered that libevent incorrectly handled certain empty output buffers. An attacker could possibly use this issue to trigger a use-after-free, resulting in a denial of service or arbitrary code execution. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.0...
