Debian DLA-355-1 : libxml2 security update

medium Nessus Plugin ID 87076
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.

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2015-8241 Buffer overread with XML parser in xmlNextChar

CVE-2015-8317

- issues in the xmlParseXMLDecl function: If we fail conversing the current input stream while processing the encoding declaration of the XMLDecl then it's safer to just abort there and not try to report further errors.

- If the string is not properly terminated do not try to convert to the given encoding.

Additional fix for off by one error in previous patch for CVE-2015-7942 (thanks to Salvatore for spotting this)

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
