The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3412-1 advisory. - CVE-2026-62343: heap buffer overwrite in morphology operation when an invalid kernel is provided bsc1272575. - CVE-2026-62946: integer overfl...

The vulnerability of the MNG encoder in the console-based image editing tool ImageMagick allows a hacker to execute arbitrary code.

The vulnerability of the MNG encoder in the console-based image editing tool ImageMagick is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability allows an attacker to execute arbitrary code...

The vulnerability of the ConnectedComponentsImage() function in the ImageMagick console graphics editor allows a hacker to cause a service failure or execute arbitrary code.

The vulnerability of the ConnectedComponentsImage function in the console-based image editing tool ImageMagick is related to reading data beyond the permitted range of memory. Exploiting this vulnerability could allow an attacker to cause a service failure or execute arbitrary code...

SUSE CVE-2026-64685

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-27, the BGR decoder does not check for an end-of-file in every location so a crafted image could result in an heap buffer over-read. This issue has been fixed in version...

JLSEC-2026-876

ImageMagick before 6.9.11-40 and 7.x before 7.0.10-40 mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via...

JLSEC-2026-977 ImageMagick has a Path Policy TOCTOU symlink race bypass

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, domain="path" authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This...

JLSEC-2026-839

In ImageMagick before 7.0.8-25, a memory leak exists in WriteDIBImage in coders/dib.c...

JLSEC-2026-987 ImageMagick has heap buffer overflow in WriteXWDImage due to CARD32 arithmetic overflow in bytes_per_line calculation

A 32-bit unsigned integer overflow in the XWD X Windows encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur. ================================================================= ==741961==ERROR: AddressSanitizer:...

JLSEC-2026-832

ImageMagick before 7.0.8-55 has a use-after-free in DestroyStringInfo in MagickCore/string.c because the error manager is mishandled in coders/jpeg.c...

JLSEC-2026-843

There are 4 places in HistogramCompare in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and count value for a color. The patch uses casts to ssizet type for these calculations, instead of int. This flaw could impact...

JLSEC-2026-1031 ImageMagick has Null Pointer Dereference caused by the distort operation when passing incorrect arguments

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-50 and 7.1.2-25, when passing incorrect arguments in the distort operation a null pointer deference will occur. This issue has been patched in versions 6.9.13-50 and 7.1.2-25...

JLSEC-2026-992 ImageMagick has an Out-of-bounds Write via InterpretImageFilename

Due to an incorrect return value on certain platforms a pointer is incremented past the end of a buffer that is on the stack and that could result in an out of bounds write. ================================================================= ==48558==ERROR: AddressSanitizer: stack-buffer-overflow o...

JLSEC-2026-928 ImageMagick CLAHE : Unsigned underflow and division-by-zero lead to OOB pointer arithmetic and process crash (DoS)

Summary A single root cause in the CLAHE implementation — tile width/height becoming zero — produces two distinct but related unsafe behaviors. Vulnerabilities exists in the CLAHEImage function of ImageMagick’s MagickCore/enhance.c. 1. Unsigned integer underflow → out-of-bounds pointer arithmetic...

JLSEC-2026-899

A vulnerability was found in ImageMagick, causing an outside the range of representable values of type 'unsigned long' at coders/pcl.c, when crafted or untrusted input is processed. This leads to a negative impact to application availability or other problems related to undefined behavior...

JLSEC-2026-1064 ImageMagick before 7.1.2-26 contains a policy bypass vulnerability in the APNG encoder and...

ImageMagick before 7.1.2-26 contains a policy bypass vulnerability in the APNG encoder and external delegates due to missing validation checks. Attackers can write files to disallowed paths by bypassing configured policy restrictions through the APNG encoding process...

JLSEC-2026-967 ImageMagick has a possible infinite loop in its JPEG encoder when using `jpeg:extent`

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 continue statement in the JPEG extent binary search loop in the jpeg encoder causes an infinite loop when writing persistently fails. An attacker can trigger ...

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-2026-860

A flaw was found in ImageMagick in coders/hdr.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 char. This would most likely lead to an impact to application availability, but could...

JLSEC-2026-973 ImageMagick vulnerable to stack corruption through long morphology kernel names or arrays

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, a stack buffer overflow exists in ImageMagick's morphology kernel parsing functions. User-controlled kernel strings exceeding a buffer are copied into fixed-siz...
