Description Mark J. Cox 2007-12-22 08:32:49 UTC

VMWare reported a buffer overflow vulnerability in the PAM authentication code
in the OpenPegasus CIM management server. This vulnerability can be exploited
remotely and results in arbitrary code execution with the privileges of the
cimserver process.

Details in next comment.

Due to the nature of the bug, and the Red Hat changes to tog-pegasus package,
it's quite likely it has a much reduced impact, this will have to be investigated.

Current embargo is Dec 27th.  I've asked for an extension to Jan 3rd at the
earliest.

Comment 2 Mark J. Cox 2007-12-22 08:35:04 UTC

There were some changes made to authentication code for Red Hat version, these
need to be checked

The sprintf is unfortunately not caught by fortify_source (because it's C++)

We do ship with a SELinux policy by default (it was a requirement of shipping
this package)

Comment 3 Mark J. Cox 2007-12-22 12:37:54 UTC

Not vulnerable.  The RHEL4 and RHEL5 builds of tog-pegasus do not build with
PEGASUS_USE_PAM_STANDALONE_PROC and therefore do not compile the vulnerable
function.

Comment 7 Mark J. Cox 2008-01-08 08:44:35 UTC

Whilst this issue does not affect Red Hat Enterprise Linux tog-pegasus packages,
we found a similar issue that does.  Please see
