Last Modification Time: 2021-01-14
Plugin Version: 1.27
Plugin Type: local

Required KB Items [?]: Host/cpu, Host/local_checks_enabled, Host/RedHat/release, Host/RedHat/rpm-list

Vulnerability Information

Severity: High
Vulnerability Published: 2007-10-12
Patch Published: 2007-10-11
CVE [?]: CVE-2007-5208
CPE [?]: cpe:/o:redhat:enterprise_linux:5, p-cpe:/a:redhat:enterprise_linux:hpijs, p-cpe:/a:redhat:enterprise_linux:hplip, p-cpe:/a:redhat:enterprise_linux:libsane-hpaio

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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 Red Hat Enterprise 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.

Solution

Update the affected hpijs, hplip and / or libsane-hpaio packages.

Public Exploits
