DESCRIPTION:
Some vulnerabilities have been reported in CUPS, which can be
exploited by malicious people to conduct cross-site request forgery
attacks, disclose potentially sensitive information, cause a DoS
(Denial of Service), or potentially compromise a vulnerable system.

1) An error due to missing memory allocation checks in the "texttops"
filter can be exploited to cause a heap corruption and potentially
execute arbitrary code.

2) An uninitialised memory access error in the CUPS web interface
when handling form variables can be exploited to disclose potentially
sensitive "cupsd" memory.

3) The CUPS web interface allows users to perform certain actions via
HTTP requests without performing any validity checks to verify the
requests. This can be exploited to e.g. change CUPS settings when a
logged-in administrative user visits a malicious web site.

The vulnerabilities are reported in versions prior to 1.4.4.

SOLUTION:
Update to version 1.4.4.
