New! Plugin Severity Now Using CVSS v3

Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Laurent Gaffie discovered that Ruby did not properly check for memory allocation failures. If a user or automated system were tricked into running a malicious script, an attacker could cause a denial of service. (CVE-2008-3443)This update also fixes a regression in the upstream patch previously applied to fix CVE-2008-3790. The regression would cause parsing of some XML documents to fail.
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.
