Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, there was a vulnerability where a memory allocation failure in the sixel encoder could lead to writing beyond the end of a buffer on the stack. This vulnerability...

JLSEC-2026-989

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-16 and 6.9.13-41, when a memory allocation fails in the sixel encoder it would be possible to write past the end of a buffer on the stack. This vulnerability is fixed in 7.1.2-16 and...

USN-8592-1 imagemagick vulnerabilities

Hao Ren discovered that ImageMagick incorrectly handled certain images when using the wavelet-denoise operation. An attacker could possibly use this issue to trigger an out-of-bounds heap write, resulting in arbitrary code execution. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS,...

DEBIAN-CVE-2026-44636

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, signed integer overflow in sixelencodehighcolor's allocation size calculation can lead to a heap buffer overflow. The public sixelencode entry point validates only that width and height are greater th...

Libstb SIXEL DoS

The vulnerability of the stbimage.h component in the C/C++ Libstb library, which implements the SIXEL Libsixel encoder/decoder, is related to pointer dereferencing errors. Exploiting this vulnerability could allow an attacker to cause a service failure by using a specially created PICT file...
