CVE-ID: CVE-2019-19721

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within DecodeBlock in sdl_image.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger a one byte out-of-bounds read error and read contents of memory on the system.

Mitigation

Update the affected package vlc to the latest version.

Vulnerable software versions

Ubuntu: 16.04 - 22.10
