CUPS: Multiple vulnerabilities

CUPS: Multiple vulnerabilities Multiple errors in CUPS might allow for the remote execution of arbitrary code or DNS rebinding attacks. cups 2009-04-23 2009-04-23 263070 remote 1.3.10 1.3.10

CUPS, the Common Unix Printing System, is a full-featured print server.

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.

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.

There is no known workaround at this time.

All CUPS users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-print/cups-1.3.10"
