In RestoreMSCWarning of /coders/pdf.c there are several areas where calls to GetPixelIndex could result in values outside the range of representable for the unsigned char type. The patch casts the return value of GetPixelIndex to ssizet type to avoid this bug. This undefined behavior could be...

JLSEC-2026-981 ImageMagick: Integer overflow in DIB coder can result in out of bounds read or write

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, an integer overflow in DIB coder can result in out of bounds read or write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41...

There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported tha...

JLSEC-2026-887

A flaw was found in ImageMagick in versions 7.0.11, where an integer overflow in WriteTHUMBNAILImage of coders/thumbnail.c may trigger undefined behavior via a crafted image file that is submitted by an attacker and processed by an application using ImageMagick. The highest threat from this...

JLSEC-2026-825

In coders/bmp.c in ImageMagick before 7.0.8-16, an input file can result in an infinite loop and hang, with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file...

JLSEC-2026-870

A flaw was found in ImageMagick in coders/bmp.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned int. This would most likely lead to an impact to application availability, but could...

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-2026-1059 ImageMagick before 7.1.2-15 (and 6.x before 6.9.13-40) contains a heap out-of-bounds read in the...

ImageMagick before 7.1.2-15 and 6.x before 6.9.13-40 contains a heap out-of-bounds read in the PCD coder's DecodeImage loop. A crafted PCD file can trigger a one-byte heap out-of-bounds read during image decoding, resulting in denial of service and potential disclosure of an adjacent heap byte...

JLSEC-2026-908

A heap-based buffer overflow vulnerability was found in coders/tiff.c in ImageMagick. This issue may allow a local attacker to trick the user into opening a specially crafted file, resulting in an application crash and denial of service...

JLSEC-2026-856

A flaw was found in ImageMagick in coders/txt.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long long. This would most likely lead to an impact to application availability, but...

A vulnerability was found in ImageMagick. This security flaw ouccers as an undefined behaviors of casting double to sizet in svg, mvg and other coders recurring bugs of CVE-2022-32546...

JLSEC-2026-879

A flaw was found in ImageMagick in coders/jp2.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat from this vulnerability is to system availability...

JLSEC-2026-845

WriteOnePNGImage from coders/png.c the PNG coder has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times,...

JLSEC-2026-1011 ImageMagick: Policy Bypass in MNG coder could

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-47 and 7.1.2-22, because of a missing check in the MNG coder it would be possible to read more images than the list limit policy would allow resulting in excessive resource use...

JLSEC-2026-842

The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory in routine WritePALMImage because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytesperrow in the call to AcquireQuantumMemory. This could cause...
