CVE-2009-0196: ghostscript: Missing boundary check in Ghostscript's jbig2dec library

Severity: Critical

CVSS Score: 9.3

Heap-based buffer overflow in the big2_decode_symbol_dict function (jbig2_symbol_dict.c) in the JBIG2 decoding library (jbig2dec) in Ghostscript 8.64, and probably earlier versions, allows remote attackers to execute arbitrary code via a PDF file with a JBIG2 symbol dictionary segment with a large run length value.
