Security Bulletin
This security bulletin contains information about 7 vulnerabilities.
1) Out-of-bounds read
EUVDB-ID: #VU27925
Risk: Low
CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-19721
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package vlc to the latest version.
Vulnerable software versionsUbuntu: 16.04 - 22.10
