TITLE:
Fedora update for systemtap

SECUNIA ADVISORY ID:
SA37167

VERIFY ADVISORY:
http://secunia.com/advisories/37167/

DESCRIPTION:
Fedora has acknowledged some vulnerabilities in systemtap, which can
be exploited by malicious, local users to cause a DoS (Denial of
Service).

1) A stack overflow exists when handling a large amount of parameters
passed to formatted printing functions, which can be exploited to
cause a kernel crash.

2) An error exists within the handling of certain DWARF expressions.
This can be exploited to cause a kernel crash by providing specially
crafted DWARF information.

3) An error exists within the handling of unwind tables, which can be
exploited to cause an infinite loop.

Note: Successful exploitation requires that the "--unprivileged" mode
is used, which is not enabled by default.

SOLUTION:
Apply updated packages using the yum utility ("yum update
systemtap").

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
