Package : openh264
CVE ID : CVE-2025-27091
Debian Bug : 1098470
A heap-based buffer overflow flaw in the decoding functions of openh264,
a codec library which supports H.264 encoding and decoding, may allow a
remote attacker to cause a denial of service or the execution of
arbitrary code if a specially crafted video is processed.
For the stable distribution (bookworm), this problem has been fixed in
version 2.3.1+dfsg-3+deb12u1.
We recommend that you upgrade your openh264 packages.
