tiff vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

– Ubuntu 16.04 ESM
– Ubuntu 14.04 ESM


Several security issues were fixed in LibTIFF.

Software Description:
– tiff: Tag Image File Format (TIFF) library


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. This issue was only fixed in Ubuntu 14.04 ESM.
(CVE-2019-14973, CVE-2019-17546, CVE-2020-35523, CVE-2020-35524,

It was discovered that LibTIFF was incorrectly acessing a data structure
when processing data with the tiffcrop tool, which could lead to a heap
buffer overflow. An attacker could possibly use this issue to cause a
denial of service or execute arbitrary code. (CVE-2022-48281)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 ESM:

Ubuntu 14.04 ESM:
libtiff-tools 4.0.3-7ubuntu0.11+esm6
