SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionA Denial of Service vulnerability has been discovered in the ptrace() call on the amd64 platform. By calling ptrace() with specially crafted ('non-canonical') addresses, a local attacker could cause the kernel to crash. This only affects the amd64 platform. (CAN-2005-1762)
ZouNanHai discovered that a local user could hang the kernel by invoking syscall() with specially crafted arguments. This only affects the amd64 platform when running in the 32 bit compatibility mode.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected packages.
