========================================================================== Ubuntu Security Notice USN-4755-1 February 25, 2021
tiff vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in LibTIFF.
Software Description: - tiff: Tag Image File Format (TIFF) library
Details:
It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10: libtiff-tools 4.1.0+git191117-2ubuntu0.20.10.1 libtiff5 4.1.0+git191117-2ubuntu0.20.10.1
Ubuntu 20.04 LTS: libtiff-tools 4.1.0+git191117-2ubuntu0.20.04.1 libtiff5 4.1.0+git191117-2ubuntu0.20.04.1
Ubuntu 18.04 LTS: libtiff-tools 4.0.9-5ubuntu0.4 libtiff5 4.0.9-5ubuntu0.4
Ubuntu 16.04 LTS: libtiff-tools 4.0.6-1ubuntu0.8 libtiff5 4.0.6-1ubuntu0.8
In general, a standard system update will make all the necessary changes.
