Debian DSA-2652-1 : libxml2 - external entity expansion

medium Nessus Plugin ID 65695
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Brad Hill of iSEC Partners discovered that many XML implementations are vulnerable to external entity expansion issues, which can be used for various purposes such as firewall circumvention, disguising an IP address, and denial-of-service. libxml2 was susceptible to these problems when performing string substitution during entity expansion.


Upgrade the libxml2 packages.

For the stable distribution (squeeze), these problems have been fixed in version 2.7.8.dfsg-2+squeeze7.
