Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2023-04-29 22:37:32 UTC 
CVE-2022-4904:

A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity.

Patch is in 1.19.0: https://github.com/c-ares/c-ares/commit/9903253c347f9e0bffd285ae3829aef251cc852d

Please cleanup.
