3. Description:

 

SystemTap is an instrumentation system for systems running the Linux

kernel. The system allows developers to write scripts to collect data on

the operation of the system.

 

An invalid pointer read flaw was 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 this flaw to crash the system or, potentially, read arbitrary

kernel memory. Additionally, a privileged user (root, or a member of the

stapdev group) could trigger this flaw when tricked into instrumenting a

specially-crafted ELF binary, even when unprivileged mode was not enabled.

(CVE-2012-0875)

 

SystemTap users should upgrade to these updated packages, which contain a

backported patch to correct this issue.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to

use the Red Hat Network to apply this update are available at

https://access.redhat.com/knowledge/articles/11258

 

5. Bugs fixed (http://bugzilla.redhat.com/):
