[ MDVSA-2010:073 ] cups

[dude67]

_______________________________________________________________________

Package : cups
Date : April 14, 2010
Affected: 2008.0, 2009.0, 2009.1, Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in cups:

CUPS in does not properly handle (1) HTTP headers and (2) HTML
templates, which allows remote attackers to conduct cross-site
scripting (XSS) attacks and HTTP response splitting attacks via vectors
related to (a) the product's web interface, (b) the configuration of
the print system, and (c) the titles of printed jobs (CVE-2009-2820).

Use-after-free vulnerability in the abstract file-descriptor handling
interface in the cupsdDoSelect function in scheduler/select.c in the
scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers
to cause a denial of service (daemon crash or hang) via a client
disconnection during listing of a large number of print jobs, related
to improperly maintaining a reference count. NOTE: some of these
details are obtained from third party information (CVE-2009-3553).

Use-after-free vulnerability in the abstract file-descriptor handling
interface in the cupsdDoSelect function in scheduler/select.c in the
scheduler in cupsd in CUPS 1.3.7, 1.3.9, 1.3.10, and 1.4.1, when kqueue
or epoll is used, allows remote attackers to cause a denial of service
(daemon crash or hang) via a client disconnection during listing
of a large number of print jobs, related to improperly maintaining
a reference count. NOTE: some of these details are obtained from
third party information. NOTE: this vulnerability exists because of
an incomplete fix for CVE-2009-3553 (CVE-2010-0302).

The _cupsGetlang function, as used by lppasswd.c in lppasswd in CUPS
1.2.2, 1.3.7, 1.3.9, and 1.4.1, relies on an environment variable
to determine the file that provides localized message strings, which
allows local users to gain privileges via a file that contains crafted
localization data with format string specifiers (CVE-2010-0393).

The updated packages have been patched to correct these issues.
