 - ----------------------------------------------------------------------- Debian LTS Advisory DLA-4507-1 [email protected] https://www.debian.org/lts/security/ Utkarsh Gupta March 23, 2026 https://wiki.debian.org/LTS
 - -----------------------------------------------------------------------

 Package : vlc Version : 3.0.23-0+deb11u1 CVE ID : CVE-2025-51602

 An out-of-bounds read vulnerability was discovered in VLC media player, a multimedia player and streamer. The MMS protocol handler in mmstu.c did not properly validate boundaries when processing a crafted 0x01 response from an MMS server. A remote attacker controlling a malicious MMS server could exploit this to cause an out-of-bounds read, resulting in a denial of service (application crash) and potentially leaking sensitive memory contents.

 For Debian 11 bullseye, this problem has been fixed in version 3.0.23-0+deb11u1.

 We recommend that you upgrade your vlc packages.

 For the detailed security status of vlc please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/vlc

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libvlc-bin packages.
