Scientific Linux Security Update : systemtap on SL6.x i386/x86_64

low Nessus Plugin ID 61062

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

SystemTap is an instrumentation system for systems running the Linux kernel, version 2.6. Developers can write scripts to collect data on the operation of the system.

Two divide-by-zero flaws were found in the way SystemTap handled malformed debugging information in DWARF format. When SystemTap unprivileged mode was enabled, an unprivileged user in the stapusr group could use these flaws to crash the system. Additionally, a privileged user (root, or a member of the stapdev group) could trigger these flaws when tricked into instrumenting a specially crafted ELF binary, even when unprivileged mode was not enabled. (CVE-2011-1769, CVE-2011-1781)

SystemTap users should upgrade to these updated packages, which contain a backported patch to correct these issues.

Solution

Update the affected packages.
