Test ID:1.3.6.1.4.1.25623.1.0.51185
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2005:013
Summary:Redhat Security Advisory RHSA-2005:013
Description:
The remote host is missing updates announced in
advisory RHSA-2005:013.

The Common UNIX Printing System provides a portable printing layer for
UNIX(R) operating systems.

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 CVE-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
CVE-2004-1267 to this issue.

Red Hat believes that the Exec-Shield technology (enabled by default since
Update 3) will block attempts to exploit these buffer overflow
vulnerabilities on x86 architectures.

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 CVE-2004-1268 and CVE-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
CVE-2004-1270 to this issue.

In addition to these security issues, two other problems not relating
to security have been fixed:

Resuming a job with lp -H resume, which had previously been held with lp
- -H hold could cause the scheduler to stop. This has been fixed in later
versions of CUPS, and has been backported in these updated packages.

The cancel-cups(1) man page is a symbolic link to another man page. The
target of this link has been corrected.

All users of cups should upgrade to these updated packages, which resolve
these issues.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
