Fedora 13 : systemtap-1.4-6.fc13 (2011-7289)

high Nessus Plugin ID 54835

Language:

Synopsis

The remote Fedora host is missing a security update.

Description

Two divide-by-zero flaws were found in the way systemtap interpreted certain corrupted DWARF expressions. A privileged user able to execute arbitrary systemtap scripts could be tricked into triggering this flaw to crash the target machine. An unprivileged user (in the stapusr group) may be able to trigger this flaw to crash the target machine, only if unprivileged mode was enabled by the system administrator.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected systemtap package.
