Vulnerabilidades de Imagemagick

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 crafted highly compressed MAT image can make the MAT decoder create temporary files larger than the configured security-policy limit, bypassing resource restrictions and consuming excessive disk space. This issue is fixed in versions 7.1.2-30 and 6.9.13-55.

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, when ImageMagick is built without Cairo support, a crafted RSVG image that reaches a resource limit can cause the RSVG decoder to free image state twice and then use freed memory, crashing the process. This issue is fixed in versions 7.1.2-30 and 6.9.13-55.

ImageMagick is free and open-source software used for editing and manipulating digital images.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31, a crafted XMP profile can trigger excessive work while the parser determines a rational value's numerator and denominator, causing denial of service. This issue is fixed in version 7.1.2-31.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31, a crafted Magick script can cause an opened file pointer to remain unclosed, allowing repeated processing to exhaust available file descriptors. This issue is fixed in version 7.1.2-31.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31, a client connected to the distributed pixel cache server can send crafted pixel data that triggers an integer-size calculation error and a heap buffer overwrite, crashing the server. This issue is fixed in version 7.1.2-31.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31 and 6.9.13-56, a missing limit check in the MVG decoder allows a crafted MVG image to trigger an excessively long-running operation. This issue is fixed in versions 7.1.2-31 and 6.9.13-56.

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 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 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 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 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 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 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 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 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 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 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.
