An updated hplip package to correct a security flaw is now available for Red
Hat Enterprise Linux 5.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
The hplip (Hewlett-Packard Linux Imaging and Printing Project) package
provides drivers for HP printers and multi-function peripherals.
Kees Cook discovered a flaw in the way the hplip hpssd daemon handled user
input. A local attacker could send a specially crafted request to the hpssd
daemon, possibly allowing them to run arbitrary commands as the root user.
(CVE-2007-5208). On CentOS Linux 5, the SELinux targeted
policy for hpssd which is enabled by default, blocks the ability to exploit
this issue to run arbitrary code.
Users of hplip are advised to upgrade to this updated package, which
contains backported patches to resolve this issue.
