=========================================================== Ubuntu Security Notice USN-674-1 November 19, 2008 hplip vulnerabilities CVE-2008-2940, CVE-2008-2941 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. 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)

If a user were tricked into opening a malicious website, an attacker could send a crafted header in the HTTP index response, causing a browser crash and execute arbitrary code with user privileges. (CVE-2008-0017) A flaw was discovered in Firefox's DOM constructing code. If a user were tricked into opening a malicious website, an attacker could cause the browser to crash and potentially execute arbitrary code with user privileges. (CVE-2008-5021) It was discovered that the same-origin check in Firefox could be bypassed. If a user were tricked into opening a malicious website, an attacker could execute JavaScript in the context of a different website.

An attacker could exploit this to gain root privileges to the virtual machine by using a predictable password. This vulnerability only affects virtual machines created with vm-builder under Ubuntu 8.10, and does not affect native Ubuntu installations. An update was made to the shadow package to detect vulnerable systems and disable password authentication for the root account. Vulnerable virtual machines which an attacker has access to should be considered compromised, and appropriate actions taken to secure the machine.
