Description
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.
