Updated CUPS packages that fix several security issues are now available.
The Common UNIX Printing System provides a portable printing layer for UNIX(R) operating systems.

During a source code audit, Chris Evans discovered a number of integer overflow bugs that affect xpdf. CUPS contains a copy of the xpdf code used for parsing PDF files and is therefore affected by these bugs. An attacker who has the ability to send a malicious PDF file to a printer could cause CUPS to crash or possibly execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0888 to this issue.
When set up to print to a shared printer via Samba, CUPS would authenticate with that shared printer using a username and password. By default, the username and password used to connect to the Samba share is written into the error log file. A local user who is able to read the error log file could collect these usernames and passwords. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0923 to this issue.
A buffer overflow was found in the CUPS pdftops filter, which uses code from the Xpdf package. An attacker who has the ability to send a malicious PDF file to a printer could possibly execute arbitrary code as the "lp" user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1125 to this issue.
A buffer overflow was found in the ParseCommand function in the hpgltops program. An attacker who has the ability to send a malicious HPGL file to a printer could possibly execute arbitrary code as the "lp" user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1267 to this issue.
The lppasswd utility ignores write errors when modifying the CUPS passwd file. A local user who is able to fill the associated file system could corrupt the CUPS password file or prevent future uses of lppasswd. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-1268 and CAN-2004-1269 to these issues.
The lppasswd utility does not verify that the passwd.new file is different from STDERR, which could allow local users to control output to passwd.new via certain user input that triggers an error message. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1270 to this issue.
A buffer overflow flaw was found in the Decrypt::makeFileKey2 function of Xpdf which also affects the CUPS pdftops filter due to a shared codebase. An attacker who has the ability to send a malicious PDF file to a printer could possibly execute arbitrary code as the "lp" user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0064 to this issue.
All users of cups should upgrade to these updated packages, which resolve these issues.
Before applying this update, make sure all previously released errata relevant to your system have been applied.
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get.
