Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins." • ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2006.15/SCOSA-2006.15.txt ftp://patches.sgi.com/support/free/security/advisories/20051201-01-U ftp://patches.sgi.com/support/free/security/advisories/20060101-01-U ftp://patches.sgi.com/support/free/security/advisories/20060201-01-U http://lists.suse.com/archive/suse-security-announce/2006-Jan/0001.html http://rhn.redhat.com/errata/RHSA-2006-0177.html http://scary.beasts.org/security/CESA-2005-003.txt http://secunia.com/ • CWE-399: Resource Management Errors •
