high Nessus Plugin ID 105037

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

Wei Lei discovered that libxml2 incorrecty handled certain parameter entities. An attacker could use this issue with specially constructed XML data to cause libxml2 to consume resources, leading to a denial of service.

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

Solution

Update the affected packages.
