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

- Ubuntu 26.04 LTS
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in ImageMagick.

Software Description:
- imagemagick: Image manipulation programs and library

Details:

It was discovered that ImageMagick did not limit mutual references between
MVG files. An attacker could possibly use this issue to cause a stack
overflow, resulting in a denial of service. This issue only affected Ubuntu
14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu
22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2025-68950)

It was discovered that the ImageMagick MSL coder destroyed a cloned image
twice when an MSL script failed. An attacker could possibly use this issue
to cause a use-after-free, resulting in a denial of service, or arbitrary
code execution. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04
LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04
LTS. (CVE-2026-28688)

It was discovered that the ImageMagick VIFF image encoder did not properly
validate the packet count, leading to an integer overflow on 32-bit
systems. An attacker could possibly use this issue to cause an out-of-
bounds heap write, resulting in a denial of service. (CVE-2026-33900)

It was discovered that ImageMagick did not properly handle the column
offset when sampling an image. An attacker could possibly use this issue to
cause ImageMagick to read out of bounds, resulting in a denial of service.
This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04
LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS.
(CVE-2026-33905)
