Resumen:	The remote host is missing an update for the 'systemtap'; package(s) announced via the referenced advisory.
Descripción:	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. Two divide-by-zero flaws were 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 these flaws to crash the system. Additionally, a privileged user (root, or a member of the stapdev group) could trigger these flaws when tricked into instrumenting a specially-crafted ELF binary, even when unprivileged mode was not enabled. (CVE-2011-1769, CVE-2011-1781) SystemTap users should upgrade to these updated packages, which contain a backported patch to correct these issues. Affected Software/OS: systemtap on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 1.2 CVSS Vector: AV:L/AC:H/Au:N/C:N/I:N/A:P
