Description Jan Lieskovsky 2012-03-08 10:42:26 UTC

An information disclosure flaw was found in the way phpCAS, the Central Authentication Service client library in PHP language, performed archiving of debug logging file in the default debug configuration and archiving of proxy configuration session data. Both of the files were archived in /tmp directory in files with unsafe permissions. A local attacker could use this flaw to obtain private user attributes and sensitive login tokens by inspecting content of those archived files.

This issue affects the versions of the php-pear-CAS package, as shipped with
Fedora EPEL 5 and Fedora EPEL 6. Please schedule an update.

Comment 2 Jan Lieskovsky 2012-03-08 10:45:34 UTC

Created php-pear-CAS tracking bugs for this issue

Affects: fedora-all [bug 801349]
Affects: epel-all [bug 801350]

Comment 3 Jan Lieskovsky 2012-03-08 11:07:22 UTC

Also, the versions of the glpi package, as shipped with Fedora release of 15, 16, Fedora EPEL 5 and EPEL 6 use system version of php-pear-CAS library:

* Thu May 20 2010 Remi Collet <Fedora> - 0.72.4-3.svn11497
- use system phpCAS instead of bundled copy
- minor bug fixes from SVN

and thus are not affected by this issue once the deficiency in php-pear-CAS package has got addressed.

Comment 4 Jan Lieskovsky 2012-03-08 11:16:33 UTC

The versions of the moodle package, as shipped with Fedora release of 15, 16, Fedora EPEL 5 and EPEL 6 are also using system version of the php-pear-CAS package:

EPEL-5 case:
* Fri Aug 20 2010 Jon Ciesla <limb> - 1.8.13-2
- Switch to system php-pear-CAS, BZ 577467, 620772.

F-16 case:
* Thu Aug 19 2010 Jon Ciesla <limb> - 1.9.9-2
- Switch to system php-pear-CAS, BZ 577467, 620772.
- Patching htmlpurifier, BZ 624754.

and as such are not vulnerable to this issue, once this flaw has been corrected in php-pear-CAS package.
