Linux amd64 kernel vulnerabilities

Releases

• Ubuntu 5.04
• Ubuntu 4.10

Details

A 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.
