The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: hplip 0.9.7-4ubuntu1.1 Ubuntu 7.10: hplip 2.7.7.dfsg.1-0ubuntu5.1 Ubuntu 8.04 LTS: hplip 2.8.2-0ubuntu8.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: 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)
