The dissect_pft function in epan/dissectors/packet-dcp-etsi.c in the DCP ETSI dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a zero-length message.

The CIP dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 allows remote attackers to cause a denial of service (memory consumption) via a malformed packet.

epan/dissectors/packet-afp.c in the AFP dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 allows remote attackers to cause a denial of service (loop and CPU consumption) via a large number of ACL entries.

The CTDB dissector in Wireshark 1.4.x before 1.4.15, 1.6.x before 1.6.10, and 1.8.x before 1.8.2 allows remote attackers to cause a denial of service (loop and CPU consumption) via a malformed packet.

The actions implementation in the network queueing functionality in the Linux kernel before 2.6.36-rc2 does not properly initialize certain structure members when performing dump operations, which allows local users to obtain potentially sensitive information from kernel memory via vectors related to (1) the tcf_gact_dump function in net/sched/act_gact.c, (2) the tcf_mirred_dump function in net/sched/act_mirred.c, (3) the tcf_nat_dump function in net/sched/act_nat.c, (4) the tcf_simp_dump function in net/sched/act_simple.c, and (5) the tcf_skbedit_dump function in net/sched/act_skbedit.c.

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

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.

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.
