ImageMagick 7.1.0-21 before 7.1.2-32 contains a heap buffer over-read in its handling of the -fx option, where a certain -fx operation reads beyond the bounds of an allocated heap buffer in specific situations. Attackers who can get a crafted -fx expression processed can read out-of-bounds heap memory, potentially disclosing limited memory contents.
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the JPEG decoder, which performs a read that exposes uninitialized memory when handling crafted input. Attackers can supply a crafted JPEG file for processing to disclose uninitialized memory contents.
ImageMagick before 7.1.2-32 contains a memory leak vulnerability in the -process option that allows attackers to cause unreleased memory allocations by supplying certain arguments. Attackers can repeatedly invoke the -process option with crafted arguments to gradually exhaust memory and degrade service availability.
ImageMagick 7.1.2-30 before 7.1.2-32 contains a use after free vulnerability in the WBINFO decoder that occurs when a memory allocation fails during image decoding. Attackers can supply a crafted image that, when decoded under memory allocation failure conditions, causes freed memory to be reused, crashing the application.
ImageMagick 7.1.1-31 before 7.1.2-32 contains a NULL pointer dereference in the PostScript decoder that is triggered when a policy limit is reached. Attackers can supply a crafted PostScript file for processing to crash the application, causing a denial of service.
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the PostScript decoder, which allocates a buffer one byte longer than the data it decoded. Attackers can supply a crafted PostScript file to expose a single uninitialized byte of memory contents.
ImageMagick before 7.1.2-32 contains a time-of-check time-of-use symlink race vulnerability that allows attackers to bypass the path security policy when executing a magick script. Attackers can swap a checked path with a symlink during script execution to read files that the security policy is meant to block.
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a code injection vulnerability in the MVG decoder when a PostScript renderer is used. Attackers can supply a crafted MVG file that, when decoded, injects code into the PostScript rendering path.
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the SVG encoder (WriteSVGImage) that fails to release allocated memory when handling crafted images. Attackers can supply crafted image files that are processed by the SVG encoder to leak memory and cause a denial of service through resource consumption.
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the YUV encoder, which fails to release allocated memory when a specific operation fails. Attackers can supply crafted input that triggers the failing encoder operation, leaking memory and potentially exhausting resources to cause a denial of service.
