CentOS Errata and Security Advisory CESA-2012:0376
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.
