Echo: ffmpeg: security update to 7:7.1.5-0+deb13u1+e5

critical Tenable Cloud Security Plugin ID 457421

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- FFmpeg before commit 1c10bcc contains a heap buffer overflow in the RIST protocol reader
(libavformat/librist.c). librist_read() ignored its size argument and copied the full received payload
length into the caller-provided destination buffer, overflowing it when the payload exceeds the
destination size. This is reachable via the async:rist:// URL scheme, where the async wrapper supplies a
smaller buffer than the received payload. A remote RIST sender can trigger the overflow by sending a
packet whose payload exceeds the caller buffer size. (CVE-2026-75143)

Solution

Update the ffmpeg library and its related packages to version 7:7.1.5-0+deb13u1+e5 or later.
