Amazon Linux AMI : systemtap (ALAS-2012-54)

medium Nessus Plugin ID 69661

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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)

Solution

Run 'yum update systemtap' to update your system.
