Synopsis
The remote Red Hat host is missing a security update for kernel.Description
The remote Redhat Enterprise Linux 4 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0676 advisory.The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issue:
* 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)
Red Hat would like to thank the X.Org security team for reporting this issue. Upstream acknowledges Rafal Wojtczuk as the original reporter.
Users should upgrade to these updated packages, which contain backported patches to correct this issue. The system must be rebooted for this update to take effect.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL kernel package based on the guidance in RHSA-2010:0676.See Also
