CVE-2011-2697 – Schwachstelle im Druck-Filter foomatic-rip (Perl)
Im Druck-Filter foomatic-rip, der Teil der Spooler unabhaengigen
Kommandozeilenschnittstelle von foomatic ist, werden Benutzereingaben
nicht hinreichend gefiltert, und Optionen eines Druckauftrages
(username, title oder job options) koennen als Optionen der Befehlszeile
ausgewertet werden. Hierdurch kann an Stelle der vom Administrator
vorgegebenen PostScript printer description (PPD) Datei eine
manipulierte uebergeben werden. Ein entfernter Angreifer kann diese
Schwachstelle ausnutzen, um beliebige Befehle mit den Rechten der
Anwendung (lp) auszufuehren.

=====================================================================
1. Summary:
An updated foomatic package that fixes one security issue is now available
for Red Hat Enterprise Linux 4 and 5.
The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,

3. Description:
Foomatic is a comprehensive, spooler-independent database of printers,
printer drivers, and driver descriptions. The package also includes
spooler-independent command line interfaces to manipulate queues and to
print files and manipulate print jobs. foomatic-rip is a print filter
written in Perl.
An input sanitization flaw was found in the foomatic-rip print filter. An
attacker could submit a print job with the username, title, or job options
set to appear as a command line option that caused the filter to use a
specified PostScript printer description (PPD) file, rather than the
administrator-set one. This could lead to arbitrary code execution with the
privileges of the “lp” user. (CVE-2011-2697)
All foomatic users should upgrade to this updated package, which contains
a backported patch to resolve this issue.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
