Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

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."

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.

Heap-based buffer overflow in the iGateway service for various Computer Associates (CA) iTechnology products, in iTechnology iGateway before 4.0.051230, allows remote attackers to execute arbitrary code via an HTTP request with a negative Content-Length field.

Heap-based buffer overflow in pskcmp.dll in Panda Software Antivirus library allows remote attackers to execute arbitrary code via a crafted ZOO archive.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.

Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete.

Tarantella Secure Global Desktop Enterprise Edition 4.00 and 3.42, and Tarantella Enterprise 3 3.40 and 3.30, when using RSA SecurID and multiple users have the same username, reveals sensitive information during authentication, which allows remote attackers to identify valid usernames and the authentication scheme.

Unknown vulnerability in the PPP driver for the Linux kernel 2.6.8.1 allows remote attackers to cause a denial of service (kernel crash) via a pppd client.
