RHSA-2006-0612: krb Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the krb packages
Detailed Explanation for this Vulnerability Test
Updated krb5 packages are now available for Red Hat Enterprise Linux 4 to
correct a privilege escalation security flaw.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
Kerberos is a network authentication system which allows clients and
servers to authenticate to each other through use of symmetric encryption
and a trusted third party, the KDC.
A flaw was found where some bundled Kerberos-aware applications would fail
to check the result of the setuid() call. On Linux 2.6 kernels, the
setuid() call can fail if certain user limits are hit. A local attacker
could manipulate their environment in such a way to get the applications to
continue to run as root, potentially leading to an escalation of
Users are advised to update to these erratum packages which contain a
backported fix to correct this issue.
