Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc//fd/ pathname.
The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clearchildtid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONECHILDSETTID or CLONECHILDCLEARTID enabled, which is not properly handled during thread creation and exit.
yast2-backup 2.14.2 through 2.16.6 on SUSE Linux and Novell Linux allows local users to gain privileges via shell metacharacters in filenames used by the backup process.
nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory.
Description of problem: To avoid exposing ourselves to the risk of finding another field like .mapbh.bstate where we rely on zeroing but don't enforce it in the code. The fix uses kzalloc to zero all the struct dio rather than manually trying to track which fields we rely on being zero.

The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) pppasync.c, (5) pppsynctty.c, (6) slip.c, (7) wan/x25asy.c, and (8) wireless/strip.c in drivers/net/.
Stack-based buffer overflow in the pammicasa PAM authentication module in CASA on Novell Linux Desktop 9 and Open Enterprise Server 1 allows remote attackers to execute arbitrary code via unspecified vectors.
Linux kernel 2.6 and 2.4 on the IA64 architecture allows local users to cause a denial of service (kernel crash) via ptrace and the restoresigcontext function.
traps.c in the Linux kernel 2.6.x and 2.4.x executes stack segment faults on an exception stack, which allows local users to cause a denial of service (oops and stack fault exception).
Buffer overflow in ptrace in the Linux Kernel for 64-bit architectures allows local users to write bytes into kernel memory.
tetex in Novell Linux Desktop 9 allows local users to determine the existence of arbitrary files via a symlink attack in the /var/cache/fonts directory.
Multiple unknown vulnerabilities in netapplet in Novell Linux Desktop 9 allow local users to gain root privileges, related to "User input [being] passed to network scripts without verification."
