========================================================================== Ubuntu Security Notice USN-8468-1 June 24, 2026
imagemagick vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- 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 incorrectly handled certain images
when using the wavelet-denoise operator. An attacker could possibly use
this issue to trigger a heap buffer over-read, resulting in information
disclosure. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,
Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2026-27798)
It was discovered that ImageMagick incorrectly handled certain DJVU
images. An attacker could possibly use this issue to trigger a heap
buffer over-read, resulting in information disclosure. (CVE-2026-27799)
It was discovered that ImageMagick incorrectly handled certain MNG
images. An attacker could possibly use this issue to trigger a stack
buffer overflow, resulting in arbitrary code execution. (CVE-2026-28690)
It was discovered that ImageMagick incorrectly handled certain JBIG
images. An attacker could possibly use this issue to trigger a pointer
dereference error, resulting in a denial of service. (CVE-2026-28691)
It was discovered that ImageMagick incorrectly handled certain MAT
images. An attacker could possibly use this issue to trigger a heap
buffer over-read, resulting in information disclosure. (CVE-2026-28692)
It was discovered that ImageMagick incorrectly handled certain DIB
images. An attacker could possibly use this issue to trigger an integer
overflow, resulting in arbitrary code execution. (CVE-2026-28693)
