USN-6428-1: LibTIFF vulnerability




Canonical Ubuntu

Versions Affected

  • Canonical Ubuntu 16.04
  • Canonical Ubuntu 18.04
  • Canonical Ubuntu 22.04


It was discovered that LibTIFF could be made to read out of bounds when processing certain malformed image files with the tiffcrop utility. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service. Update Instructions: Run `sudo pro fix USN-6428-1` to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: libtiff-opengl – 4.0.6-1ubuntu0.8+esm13 libtiffxx5 – 4.0.6-1ubuntu0.8+esm13 libtiff5-dev – 4.0.6-1ubuntu0.8+esm13 libtiff5 – 4.0.6-1ubuntu0.8+esm13 libtiff-tools – 4.0.6-1ubuntu0.8+esm13 libtiff-doc – 4.0.6-1ubuntu0.8+esm13 Available with Ubuntu Pro (Infra-only):
