Severity: normal
Exploitable: local, remote
Date: 2020-05-14
Bug(s): #721940
ID: 202005-11

Synopsis

A buffer overflow in VLC might allow local or remote attacker(s) to
execute arbitrary code.


Background

VLC is a cross-platform media player and streaming server.

Affected Packages

Package: media-video/vlc
Vulnerable: < 3.0.10
Unaffected: >= 3.0.10
Architectures: All supported architectures


Description

A buffer overflow in DecodeBlock in sdl_image.c was discovered.

Impact

A remote user could craft a specifically crafted image file that could
execute arbitrary code or cause denial of service.


Workaround

The user should refrain from opening files from untrusted third parties
or accessing untrusted remote sites (or disable the VLC browser plugins),
until they upgrade.


Resolution

All VLC users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=media-video/vlc-3.0.10"
