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 •

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows. • 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-189: Numeric Errors •

Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections. • http://mail-archives.apache.org/mod_mbox/httpd-cvs/200509.mbox/%3C20051001110218.40692.qmail%40minotaur.apache.org%3E http://rhn.redhat.com/errata/RHSA-2006-0159.html http://secunia.com/advisories/16559 http://secunia.com/advisories/17923 http://secunia.com/advisories/18161 http://secunia.com/advisories/18333 http://secunia.com/advisories/18585 http://securitytracker.com/id?1015093 http://svn.apache.org/viewcvs?rev=292949&view=rev http://www.mandriva.com/security/advisories?name= • CWE-770: Allocation of Resources Without Limits or Throttling •

The audit system in Linux kernel 2.6.6, and other versions before 2.6.13.4, when CONFIG_AUDITSYSCALL is enabled, uses an incorrect function to free names_cache memory, which prevents the memory from being tracked by AUDITSYSCALL code and leads to a memory leak that allows attackers to cause a denial of service (memory consumption). • http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=829841146878e082613a49581ae252c071057c23 http://linux.bkbits.net:8080/linux-2.6/cset%404346883bQBeBd26syWTKX2CVC5bDcA http://secunia.com/advisories/17114 http://secunia.com/advisories/17280 http://secunia.com/advisories/17364 http://secunia.com/advisories/17826 http://secunia.com/advisories/17917 http://secunia.com/advisories/19374 http://www.debian.org/security/2006/dsa-1017 http://www.mandriva.com/security& • CWE-401: Missing Release of Memory after Effective Lifetime •

Race condition in Linux 2.6, when threads are sharing memory mapping via CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a denial of service (deadlock) by triggering a core dump while waiting for a thread that has just performed an exec. • http://linux.bkbits.net:8080/linux-2.6/diffs/fs/exec.c%401.156?nav=index.html%7Csrc/%7Csrc/fs%7Chist/fs/exec.c http://secunia.com/advisories/17141 http://secunia.com/advisories/18056 http://secunia.com/advisories/18510 http://www.debian.org/security/2005/dsa-922 http://www.mandriva.com/security/advisories?name=MDKSA-2006:072 http://www.redhat.com/support/errata/RHSA-2006-0101.html http://www.securityfocus.com/archive/1/427980/100/0/threaded http://www.securi • CWE-667: Improper Locking •
