The remote Red Hat host is missing one or more security updates.
Updated cups packages that fix three security issues are now available
for Red Hat Enterprise Linux 3, 4, and 5.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The Common UNIX Printing System (CUPS) provides a portable printing
layer for UNIX operating systems. The CUPS 'texttops' filter converts
text files to PostScript.
A missing memory allocation failure check flaw, leading to a NULL
pointer dereference, was found in the CUPS 'texttops' filter. An
attacker could create a malicious text file that would cause
'texttops' to crash or, potentially, execute arbitrary code as the
'lp' user if the file was printed. (CVE-2010-0542)
A Cross-Site Request Forgery (CSRF) issue was found in the CUPS web
interface. If a remote attacker could trick a user, who is logged into
the CUPS web interface as an administrator, into visiting a
specially-crafted website, the attacker could reconfigure and disable
CUPS, and gain access to print jobs and system files. (CVE-2010-0540)
Note: As a result of the fix for CVE-2010-0540, cookies must now be
enabled in your web browser to use the CUPS web interface.
An uninitialized memory read issue was found in the CUPS web
interface. If an attacker had access to the CUPS web interface, they
could use a specially-crafted URL to leverage this flaw to read a
limited amount of memory from the cupsd process, possibly obtaining
sensitive information. (CVE-2010-1748)
