Description of problem: A vulnerability in the decoding functions of OpenH264 codec library could allow a remote, unauthenticated attacker to trigger a heap overflow. This vulnerability is due to a race condition between a Sequence Parameter Set (SPS) memory allocation and a subsequent non Instantaneous Decoder Refresh (non-IDR) Network Abstraction Layer (NAL) unit memory usage. An attacker could exploit this vulnerability by crafting a malicious bitstream and tricking a victim user into processing an arbitrary video containing the malicious bistream. An exploit could allow the attacker to cause an unexpected crash in the victim's user decoding client and, possibly, perform arbitrary commands on the victim's host by abusing the heap overflow. Version-Release number of selected component (if applicable): openh264-2.5.0-1.fc43 Additional info: Fixed in v2.6.0 (https://github.com/cisco/openh264/commit/63db555e30986e3a5f07871368dc90ae78c27449). Debian advisory: https://security-tracker.debian.org/tracker/CVE-2025-27091 .
CVSS v4 rating: 8.6 (High).
I see builds in koji, but nothing has been pushed to the codecs/open264 repo. What is the holdup?
Here is some documentation about the delay: https://pagure.io/releng/issue/12617 See "That's a very good question" in the issue discussion.
Does the following indicate this is fixed? $ rpm -q openh264 --changelog * Tue Mar 04 2025 Wim Taymans <wtaymans> - 2.6.0-2 - Remove patch to revert the Makefile major version increase. * Wed Feb 26 2025 Wim Taymans <wtaymans> - 2.6.0-1 - Update to 2.6.0 - Add patch to revert the Makefile major version increase.
