Test ID:1.3.6.1.4.1.25623.1.0.58952
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2007:0936
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory RHSA-2007:0936.

The Linux kernel handles the basic functions of the operating system.

A flaw was found in the IA32 system call emulation provided on AMD64 and
Intel 64 platforms. An improperly validated 64-bit value could be stored in
the %RAX register, which could trigger an out-of-bounds system call table
access. An untrusted local user could exploit this flaw to run code in the
kernel (ie a root privilege escalation). (CVE-2007-4573).

Red Hat would like to thank Wojciech Purczynski for reporting this issue.

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages,
which contain a backported patch to correct this issue.

Solution:

Red Hat Network. To use Red Hat Network, launch the Red
