ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the TIFF encoder when an invalid tiff:tile-geometry is specified. Supplying malformed tile geometry parameters causes allocated memory not to be released, which can lead to increased memory consumption...

JLSEC-2026-957 ImageMagick Has Signed Integer Overflow in SIXEL Decoder, Leading to Memory Corruption

A signed integer overflow vulnerability in ImageMagick's SIXEL decoder allows an attacker to trigger memory corruption and denial of service when processing a maliciously crafted SIXEL image file. The vulnerability occurs during buffer reallocation operations where pointer arithmetic using signed...

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,...

ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the ICON decoder that occurs when a memory allocation fails. Processing a crafted ICON file that triggers an allocation failure leaks memory, which may lead to a denial of service...

JLSEC-2026-959 ImageMagick has Heap Out-of-Bounds Read in DCM Decoder (ReadDCMImage)

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap out-of-bounds read vulnerability exists in the coders/dcm.c module. When processing DICOM files with a specific configuration, the decoder loop incorrect...

JLSEC-2026-946 ImageMagick has memory leak of watermark Image object in ReadSTEGANOImage on multiple error/early-return paths

Summary In ReadSTEGANOImage coders/stegano.c, the watermark Image object is not freed on three early-return paths, resulting in a definite memory leak 13.5KB+ per invocation that can be exploited for denial of service. Direct leak of 13512 bytes in 1 objects allocated from: 0 0x7f5c11e27887 in...

ImageMagick through 7.1.2-18 contains a memory leak vulnerability in the ASHLAR coder when an action fails. Attackers can trigger failed actions to exhaust memory resources and cause denial of service...

JLSEC-2026-1032 ImageMagick: Memory Leak in wand option parser when providing invalid arguments

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-25, when providing invalid options to the wand option parser a small memory leak will occur. This issue has been patched in version 7.1.2-25...

JLSEC-2026-964 ImageMagick: MSL image stack index may fail to refresh, leading to leaked images

Sometimes msl.c fails to update the stack index, so an image is stored in the wrong slot and never freed on error, causing leaks. ==841485==ERROR: LeakSanitizer: detected memory leaks Direct leak of 13512 bytes in 1 objects allocated from: 0 0x7ff330759887 in interceptormalloc...

JLSEC-2026-943 ImageMagick has memory leak in msl encoder

Memory leak exists in coders/msl.c. In the WriteMSLImage function of the msl.c file, resources are allocated. But the function returns early without releasing these allocated resources. ==78983== Memcheck, a memory error detector ==78983== Copyright C 2002-2022, and GNU GPL'd, by Julian Seward et...
