Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-12-19 21:12:05 UTC 
CVE-2021-44847 (https://github.com/TokTok/c-toxcore/pull/1718):

A stack-based buffer overflow in handle_request function in DHT.c in toxcore 0.1.9 through 0.1.11 and 0.2.0 through 0.2.12 (caused by an improper length calculation during the handling of received network packets) allows remote attackers to crash the process or potentially execute arbitrary code via a network packet.

Please bump to 0.2.13.
