Background
VLC is a cross-platform media player and streaming server.
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:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/vlc-3.0.10"
| OS | Version | Architecture | Package | Version | Filename |
