JLSEC-2026-895

In ImageMagick, a crafted file could trigger an assertion failure when a call to WriteImages was made in MagickWand/operation.c, due to a NULL image list. This could potentially cause a denial of service. This was fixed in upstream ImageMagick version 7.1.0-30...

JLSEC-2026-978 ImageMagick has stack write buffer overflow in MNG encoder

A stack buffer overflow vulnerability exists in the MNG encoder. There is a bounds checks missing that could corrupting the stack with attacker-controlled data. ==2265506==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffec4971310 at pc 0x55e671b8a072 bp 0x7ffec4970f70 sp...

JLSEC-2026-956 Image Magick has a Memory Leak in coders/ashlar.c

Memory leak exists in coders/ashlar.c. The WriteASHLARImage allocates a structure. However, when an exception is thrown, the allocated memory is not properly released, resulting in a potential memory leak. ==78968== Memcheck, a memory error detector ==78968== Copyright C 2002-2022, and GNU GPL'd,...

JLSEC-2026-934 ImageMagick releases an invalid pointer in BilateralBlur when memory allocation fails

ImageMagick is free and open-source software used for editing and manipulating digital images. The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But, in versions prior to 7.1.2-13, the last element in the set is not properly initialized. This will...
