Details

USN-674-1 provided packages to fix vulnerabilities in HPLIP. Due to an
internal archive problem, the updates for Ubuntu 7.10 would not install
properly. This update provides fixed packages for Ubuntu 7.10.

We apologize for the inconvenience.

Original advisory 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.
