The JBIG2 decoder in Xpdf 3.02pl2 and earlier, CUPS 1.3.9 and earlier, Poppler before 0.10.6, and other products allows remote attackers to execute arbitrary code via a crafted PDF file that triggers a free of invalid data.

Integer overflow in the _cupsImageReadPNG function in CUPS 1.1.17 through 1.3.9 allows remote attackers to execute arbitrary code via a PNG image with a large height value, which bypasses a validation check and triggers a buffer overflow.

Integer overflow in the WriteProlog function in texttops in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via a crafted PostScript file that triggers a heap-based buffer overflow.

Heap-based buffer overflow in the read_rle16 function in imagetops in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via an SGI image with malformed Run Length Encoded (RLE) data containing a small image and a large row count.

The Hewlett-Packard Graphics Language (HPGL) filter in CUPS before 1.3.9 allows remote attackers to execute arbitrary code via crafted pen width and pen color opcodes that overwrite arbitrary memory.
