Synopsis:	Important: cups security and bug fix update
Issue date:	2007-10-31
CVE Names:	CVE-2007-4351

A flaw was found in the way CUPS handles certain Internet Printing Protocol
(IPP) tags. A remote attacker who is able to connect to the IPP TCP port
could send a malicious request causing the CUPS daemon to crash, or
potentially execute arbitrary code. Please note that the default CUPS
configuration does not allow remote hosts to connect to the IPP TCP port.
(CVE-2007-4351)

In addition, the following bugs were fixed:

* the CUPS service has been changed to start after sshd, to avoid causing
delays when logging in when the system is booted.

* the logrotate settings have been adjusted so they do not cause CUPS to
reload its configuration. This is to avoid re-printing the current job,
which could occur when it was a long-running job.

* a bug has been fixed in the handling of the If-Modified-Since: HTTP
header.

* in the LSPP configuration, labels for labeled jobs did not line-wrap.
This has been fixed.

* an access check in the LSPP configuration has been made more secure.

* the cups-lpd service no longer ignores the "-odocument-format=..."
option.

* a memory allocation bug has been fixed in cupsd.

* support for UNIX domain sockets authentication without passwords has been
added.

* in the LSPP configuration, a problem that could lead to cupsd crashing
has been fixed.

* the error handling in the initscript has been improved.

* The job-originating-host-name attribute was not correctly set for jobs
submitted via the cups-lpd service. This has been fixed.

* a problem with parsing IPv6 addresses in the configuration file has been
fixed.

* a problem that could lead to cupsd crashing when it failed to open a
"file:" URI has been fixed.
