Description :

Rudolf Polzer reported an abuse of the 'loadkeys' command. By
redefining one or more keys and tricking another user (like root) into
logging in on a text console and typing something that involves the
redefined keys, a local user could cause execution of arbitrary
commands with the rights of the target user. The updated kernel
restricts the usage of 'loadkeys' to root. (CVE-2005-3257)

The ptrace() system call did not correctly check whether a process
tried to attach to itself. A local attacker could exploit this to
cause a kernel crash. (CVE-2005-3783)

A Denial of Service vulnerability was found in the handler that
automatically cleans up and terminates child processes that are not
correctly handled by their parent process ("auto-reaper"). The check
did not correctly handle processes which were currently traced by
another process. A local attacker could exploit this to cause a kernel
crash. (CVE-2005-3784)

A locking problem was discovered in the POSIX timer cleanup handling
on process exit. A loca
