Summary

The remote host is missing an update for the 'systemtap' package(s) announced via the referenced advisory.

Insight

Insight

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.
