JLSEC-2026-990 ImageMagick has a heap-buffer-overflow in NewXMLTree which could result in crash

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-17 and 6.9.13-42, the NewXMLTree method contains a bug that could result in a crash due to an out of write bounds of a single zero byte. Versions 7.1.2-17 and 6.9.13-42 fix the issue...

JLSEC-2026-986 ImageMagick has Heap Buffer Overflow in WaveletDenoiseImage

A crafted image could cause an out of bounds heap write inside the WaveletDenoiseImage method. When processing a crafted image with the -wavelet-denoise operation an out of bounds write can occur. ================================================================= ==661320==ERROR: AddressSanitizer:...

JLSEC-2026-1004 ImageMagick has an off-by-one error in MSL decoder could result in crash

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-19, an off by one error in the MSL decoder could result in a crash when a malicous MSL file is read. This issue has been fixed in version 7.1.2-19...

JLSEC-2026-891

A flaw was found in ImageMagick. The vulnerability occurs due to improper use of open functions and leads to a denial of service. This flaw allows an attacker to crash the system...

JLSEC-2026-900

In ImageMagick, there is load of misaligned address for type 'double', which requires 8 byte alignment and for type 'float', which requires 4 byte alignment at MagickCore/property.c. Whenever crafted or untrusted input is processed by ImageMagick, this causes a negative impact to application...

ImageMagick before 7.1.2-27 contains a memory leak vulnerability in the magick command-line interface when invalid options are provided. Attackers can trigger memory exhaustion by repeatedly supplying malformed command-line arguments to consume system resources...

JLSEC-2026-849

A flaw was found in ImageMagick in MagickCore/quantum-export.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 as well as a shift exponent that is too large for 64-bit type...

JLSEC-2026-925 ImageMagick (WriteBMPImage): 32-bit integer overflow when writing BMP scanline stride → heap buffer overflow

Summary A 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses bytesperline stride to a tiny value while the per-row writer still emits 3 × width bytes for 24-bpp images. The row base pointer advances using the overflowed stride, so the first row immediately writes...

JLSEC-2026-880

A flaw was found in ImageMagick in MagickCore/resize.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...
