USN-674-1: HPLIP vulnerabilities

Packages

• hplip -

Details

It was discovered that the hpssd tool of hplip did not validate
privileges in the alert-mailing function. A local attacker could
exploit this to gain privileges and send e-mail messages from the
account of the hplip user. This update alters hplip behaviour by
preventing users from setting alerts and by moving alert configuration
to a root-controlled /etc/hp/alerts.conf file. (CVE-2008-2940)

It was discovered that the hpssd tool of hplip did not correctly
handle certain commands. A local attacker could use a specially
crafted packet to crash hpssd, leading to a denial of service.
(CVE-2008-2941)

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.04

• hplip - 2.8.2-0ubuntu8.1

Ubuntu 7.10

• hplip - 2.7.7.dfsg.1-0ubuntu5.1

Ubuntu 6.06

necessary changes.
