All supported architectures
Multiple errors in CUPS might allow for the remote execution of arbitrary
code or DNS rebinding attacks.
CUPS, the Common Unix Printing System, is a full-featured print server.
The following issues were reported in CUPS:
reported an integer overflow in the _cupsImageReadTIFF() function in
the "imagetops" filter, leading to a heap-based buffer overflow
- 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
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"
