Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple errors in CUPS might allow for the remote execution of
arbitrary code or DNS rebinding attacks.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
CUPS, the Common Unix Printing System, is a full-featured print server.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/cups < 1.3.10 >=3D 1.3.10
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The following issues were reported in CUPS:
* iDefense reported an integer overflow in the _cupsImageReadTIFF()
function in the "imagetops" filter, leading to a heap-based buffer
overflow (CVE-2009-0163).
* Aaron Siegel of Apple Product Security reported that the CUPS web
interface does not verify the content of the "Host" HTTP header
properly (CVE-2009-0164).
* Braden Thomas and Drew Yao of Apple Product Security reported that
CUPS is vulnerable to CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166,
found earlier in xpdf and poppler.
Impact
=3D=3D=3D=3D=3D=3D
A remote attacker might send or entice a user to send a specially
crafted print job to CUPS, possibly resulting in the execution of
arbitrary code with the privileges of the configured CUPS user -- by
default this is "lp", or a Denial of Service. Furthermore, the web
interface could be used to conduct DNS rebinding attacks.
Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All CUPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dnet-print/cups-1.3.10"
