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.

SSLeay.pm in libnet-ssleay-perl before 1.25 uses the /tmp/entropy file for entropy if a source is not set in the EGD_PATH variable, which allows local users to reduce the cryptographic strength of certain operations by modifying the file.

The 55_options_traceback.dpatch patch for mailman 2.1.5 in Ubuntu 4.10 displays a different error message depending on whether the e-mail address is subscribed to a private list, which allows remote attackers to determine the list membership for a given e-mail address.

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.

The DBI library (libdbi-perl) for Perl allows local users to overwrite arbitrary files via a symlink attack on a temporary PID file.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Kommander in KDE 3.2 through KDE 3.4.0 executes data files without confirmation from the user, which allows remote attackers to execute arbitrary code.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.
