19 November 2008

hplip vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 8.04 LTS
  • Ubuntu 7.10
  • Ubuntu 6.06 LTS

Software Description

  • hplip


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)
