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.

Quoting from the upstream commit: Almost all r128's private ioctls require that the CCE state has already been initialised. However, most do not test that this has been done, and will proceed to dereference a null pointer. This may result in a security vulnerability, since some ioctls are unprivileged.

This adds a macro for the common initialisation test and changes all ioctl implementations that require prior initialisation to use that macro.

Also, r128doinitcce() does not test that the CCE state has not been initialised already. Repeated initialisation may lead to a crash or resource leak. This adds that test.

arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x8664 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.

Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp"N" device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams.

Mozilla Firefox before 3.0.12 does not always use XPCCrossOriginWrapper when required during object construction, which allows remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via a crafted document, related to a "cross origin wrapper bypass."

Buffer overflow in the utilpathencode function in udev/lib/libudev-util.c in udev before 1.4.1 allows local users to cause a denial of service (service outage) via vectors that trigger a call with crafted arguments.

A privilege escalation flaw was found in the way udev used to check for the origin of messages sent from the NETLINK service. An attacker could use this flaw to escalate his privileges by sending the NETLINK message from userspace process, instead of from the kernel.
