Test ID:1.3.6.1.4.1.25623.1.0.67902
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0660
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0660.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues:

* when an application has a stack overflow, the stack could silently
overwrite another memory mapped area instead of a segmentation fault
occurring, which could cause an application to execute arbitrary code,
possibly leading to privilege escalation. It is known that the X Window
System server can be used to trigger this flaw. (CVE-2010-2240, Important)

* a miscalculation of the size of the free space of the initial directory
entry in a directory leaf block was found in the Linux kernel Global File
System 2 (GFS2) implementation. A local, unprivileged user with write
access to a GFS2-mounted file system could perform a rename operation on
that file system to trigger a NULL pointer dereference, possibly resulting
in a denial of service or privilege escalation. (CVE-2010-2798, Important)

Red Hat would like to thank the X.Org security team for reporting
CVE-2010-2240, with upstream acknowledging Rafal Wojtczuk as the original
reporter
and Grant Diffey of CenITex for reporting CVE-2010-2798.

Solution:
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
