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...

ImageMagick Buffer Overflow Vulnerability (CNVD-2026-16617)

ImageMagick is ImageMagick open source set of open source image processing software. Can read, convert or write images in a variety of formats. ImageMagick suffers from a buffer overflow vulnerability that originates beyond the end of the write stack buffer when a memory allocation failure occurs...

CVE-2026-32259

A flaw was found in ImageMagick. Processing a specially crafted file with the sixel encoder can cause a stack-based buffer overflow when a memory allocation fails, leading to a denial of service. Mitigation To mitigate this vulnerability, disable the vulnerable encoder by adding the following lin...
