Debian DSA-2525-1 : expat - several vulnerabilities

medium Nessus Plugin ID 61441
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.


It was discovered that Expat, a C library to parse XML, is vulnerable to denial of service through hash collisions and a memory leak in pool handling.


Upgrade the expat packages.

For the stable distribution (squeeze), this problem has been fixed in version 2.0.1-7+squeeze1.
