New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7

Synopsis

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

Description

Several vulnerabilities were discovered in libxml2, a library providing support to read, modify and write XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause a denial-of-service against the application, or potentially, the execution of arbitrary code with the privileges of the user running the application.

Solution

Upgrade the libxml2 packages.

For the stable distribution (jessie), these problems have been fixed in version 2.9.1+dfsg1-5+deb8u4.
