ImageMagick: Stack Overflown CALS decoder due to missing depth check.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-30 and 6.9.13-55, a missing recursion-depth check in the CALS decoder allows a crafted CALS image to exhaust the call stack and terminate the process. This issue is fixed in versions 7.1.2-30 and 6.9.13-55.

ImageMagick: Heap Buffer Over-Write in GetVirtualPixels api will result in a crash

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 6.9.13-56 and 7.1.2-31, a crafted local call to the GetVirtualPixels API can trigger an integer calculation error and write beyond a heap buffer, crashing the server process. This issue is fixed in versions 6.9.13-56 and 7.1.2-31.

ImageMagick: Denial of service in distributed pixel cache server

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, an unauthenticated adjacent-network client can repeatedly connect to the distributed pixel cache server and exhaust its available connections, causing denial of service. This issue is fixed in version 7.1.2-32.

ImageMagick: Denial of service in ASE decoder because of missing security checks

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, missing validation and resource checks in the ASE decoder allow a crafted ASE image to cause a crash or a long-running operation. This issue is fixed in version 7.1.2-32.

ImageMagick: Infinite Loop when reading a crafted XMP profile

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32 and 6.9.13-57, a crafted XMP profile embedded in an image can cause the profile parser to enter an infinite loop, preventing image processing from completing. This issue is fixed in versions 7.1.2-32 and 6.9.13-57.

ImageMagick: Infinite Loop in PSD decoder on 32-bit builds

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32 and 6.9.13-57, a crafted PSD file can trigger an integer-conversion error in the PSD decoder on 32-bit builds, causing an infinite loop and denial of service. This issue is fixed in versions 7.1.2-32 and 6.9.13-57.

ImageMagick: Policy Bypass in delegate symlink cleanup due to missing check

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, delegate symlink cleanup does not check the MAGICK_SHRED_PASSES environment variable, allowing a local privileged workflow to overwrite a file with random data. This issue is fixed in version 7.1.2-32.

ImageMagick: Infinite Loop in bzip2 compressed images.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32 and 6.9.13-57, a missing end-of-file check while reading bzip2-compressed image data can cause an infinite loop and exhaust processing resources. This issue is fixed in versions 7.1.2-32 and 6.9.13-57.

ImageMagick: Heap Buffer Over-Write in EXR decoder

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, a crafted EXR image can cause the EXR decoder to write beyond a heap buffer, causing the process to crash. This issue is fixed in version 7.1.2-32.

ImageMagick before 7.1.2-32 and 6.9.13-57 Security Policy Bypass via policy.xml DOCTYPE

ImageMagick before 7.1.2-32 and 6.9.13-57 contains a policy bypass vulnerability in LoadPolicyCache that silently skips security policy rules when policy.xml uses an alternate DOCTYPE. A valid DOCTYPE not ending in ']>' makes the parser consume the rest of the file, so no policy rules are applied and restricted operations become allowed.

ImageMagick before 7.1.2-32 and 6.9.13-57 Uninitialized Heap Memory Disclosure in GIF Decoder

ImageMagick versions before 7.1.2-32 and 6.9.13-57 contain uninitialized heap memory disclosure in the GIF decoder's application extension handler in coders/gif.c. Attackers can craft malicious GIF files that cause the number parser to read uninitialized heap memory and store contents as image metadata, disclosing sensitive heap information.

ImageMagick before 7.1.2-31 Division by Zero in FLIF encoder

ImageMagick before 7.1.2-31 and 6.9.13-56 contains a division-by-zero flaw in the FLIF encoder. An incorrect value for ticks per second in the image being encoded causes a divide-by-zero and crashes the encoder, resulting in a denial of service. The issue is fixed in 7.1.2-31 and 6.9.13-56.

ImageMagick before 7.1.2-31 Null Pointer Dereference via PNM

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.

ImageMagick before 7.1.2-31 Policy Bypass via PCD decoder

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.

ImageMagick before 7.1.2-31 Use After Free via ImagesToBlob

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a use-after-free vulnerability in the ImagesToBlob method, caused by a pointer that is not updated correctly. Exploitation may result in a limited availability impact (e.g., a crash of the affected process). The issue is fixed in versions 7.1.2-31 and 6.9.13-56.

ImageMagick before 7.1.2-30 Heap-use-after-free via Layer

ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the Layer method of PerlMagick. An attacker who supplies a crafted list of images can trigger memory access after deallocation, resulting in a crash (denial of service).

ImageMagick before 7.1.2-30 Path Traversal via TOCTOU Symlink Race

ImageMagick before 7.1.2-30 and 6.9.13-55 contains a time-of-check-time-of-use (TOCTOU) vulnerability in the video decoder that allows attackers to bypass path policy write restrictions via symlink swaps. An attacker can replace a symlink between policy validation (check-time) and the file write operation (use-time) to write to policy-denied locations.

ImageMagick before 7.1.2-30 Heap-use-after-free via GetList

ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the GetList method of PerlMagick. A crafted call to the GetList method can trigger the use-after-free, resulting in a crash (denial of service).

ImageMagick before 7.1.2-30 Path Policy TOCTOU Symlink Race

ImageMagick before 7.1.2-30 contains a time-of-check-time-of-use vulnerability in path policy enforcement on Windows that allows attackers to bypass read or write restrictions by exploiting symlink race conditions. Attackers can swap symlinks between policy validation and file access to read or write policy-denied files.

ImageMagick before 7.1.2-30 Memory Leak via MSL decoder

ImageMagick before 7.1.2-30 and 6.9.13-55 contains a memory leak in the MSL image decoder. A crafted MSL image triggers memory allocation without proper deallocation, allowing an attacker to exhaust memory and cause a denial of service.
