(Updated kernel packages fix the AMD64 ptrace vulnerability)
A vulnerability has been discovered by Andi Kleen in the ptrace emulation
code for AMD64 platforms when eflags are processed, allowing a local user
to obtain elevated privileges. The Common Vulnerabilities and Exposures
project, http://cve.mitre.org, has assigned CAN-2004-0001 to this issue.
Only users of the AMD64 platform are affected: in this scenario, a user may
be able to obtain elevated privileges, including root access. However, no
public exploit is known for the vulnerability at this time.
There is no temporary workaround - a kernel upgrade is required. A list of
unaffected kernels is provided along with this announcement.
