Título:	RedHat Update for systemtap RHSA-2011:1088-01
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. The system allows developers to write scripts to collect data on the operation of the system. It was found that SystemTap did not perform proper module path sanity checking if a user specified a custom path to the uprobes module, used when performing user-space probing ('staprun -u'). A local user who is a member of the stapusr group could use this flaw to bypass intended module-loading restrictions, allowing them to escalate their privileges by loading an arbitrary, unsigned module. (CVE-2011-2502) A race condition flaw was found in the way the staprun utility performed module loading. A local user who is a member of the stapusr group could use this flaw to modify a signed module while it is being loaded, allowing them to escalate their privileges. (CVE-2011-2503) SystemTap users should upgrade to these updated packages, which contain backported patches 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: 4.4 CVSS Vector: AV:L/AC:M/Au:N/C:P/I:P/A:P
