Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.
The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.
Race condition in the (1) loadelflibrary and (2) binfmtaout 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.
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.
udev does not properly set permissions on certain files in /dev/input, which allows local users to obtain sensitive data that is entered at the console, such as user passwords.
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.
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.
Off-by-one error in the modssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte.
Stack-based buffer overflow in the ieeeputascii function for nasm 0.98 and earlier allows attackers to execute arbitrary code via a crafted asm file, a different vulnerability than CVE-2004-1287.
Gaim before 1.1.3 allows remote attackers to cause a denial of service (infinite loop) via malformed SNAC packets from (1) AIM or (2) ICQ.
The HTML parsing functions in Gaim before 1.1.3 allow remote attackers to cause a denial of service (application crash) via malformed HTML that causes "an invalid memory access," a different vulnerability than CVE-2005-0208.
The KAME racoon daemon in ipsec-tools before 0.5 allows remote attackers to cause a denial of service (crash) via malformed ISAKMP packets.
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.
From pcre changelog, version 6.7:
26. If a subpattern containing a named recursion or subroutine reference such as (?P>B) was quantified, for example (xxx(?P>B)){3}, the calculation of the space required for the compiled pattern went wrong and gave too small a value. Depending on the environment, this could lead to "Failed: internal error: code overflow at offset 49" or "glibc detected double free or corruption" errors.

Cross-site scripting (XSS) vulnerability in modstatus.c in the modstatus module in Apache HTTP Server (httpd), when ExtendedStatus is enabled and a public server-status page is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors involving charsets with browsers that perform "charset detection" when the content-type is not specified.
The init.d script for the X.Org X11 xfs font server on various Linux distributions might allow local users to change the permissions of arbitrary files via a symlink attack on the /tmp/.font-unix temporary file.
XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.
PerlRun.pm in Apache modperl before 1.30, and RegistryCooker.pm in modperl 2.x, does not properly escape PATHINFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.
