kernel: fs: pipe.c null pointer dereference

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.

kernel: dio: zero struct dio with kzalloc instead of manually

fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio test.

kernel: NULL ptr dereference in multiple network drivers due to missing checks in tty code

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) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.

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.

Mozilla crash and remote code execution in nsFrameManager

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.

kernel: execve: must clear current->clear_child_tid

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

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."

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.

security flaw

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 restore_sigcontext function.

security flaw

Buffer overflow in ptrace in the Linux Kernel for 64-bit architectures allows local users to write bytes into kernel memory.

security flaw

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).

Stack-based buffer overflow in the pam_micasa 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.
