Packages
- libwebp - Lossy compression of digital photographic images.
Details
It was discovered that libwebp incorrectly handled certain malformed
images. If a user or automated system were tricked into opening a specially
crafted image file, a remote attacker could use this issue to cause libwebp
to crash, resulting in a denial of service, or possibly execute arbitrary
code.
