Title:	CentOS Update for systemtap CESA-2011:0841 centos5 x86_64
Summary:	The remote host is missing an update for the 'systemtap'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'systemtap' package(s) announced via the referenced advisory. Vulnerability Insight: 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. A divide-by-zero 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. 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-2011-1769) SystemTap users should upgrade to these updated packages, which contain a backported patch to correct this issue. Affected Software/OS: systemtap on CentOS 5 Solution: Please install the updated packages. CVSS Score: 1.2 CVSS Vector: AV:L/AC:H/Au:N/C:N/I:N/A:P
