medium Nessus Plugin ID 65980
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 Ubuntu host is missing a security-related patch.

Description

It was discovered that HAProxy incorrectly handled configurations where global.tune.bufsize was set to a value higher than the default.
A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2012-2942)

Yves Lafon discovered that HAProxy incorrectly handled HTTP keywords in TCP inspection rules when HTTP keep-alive is enabled. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2013-1912).

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 haproxy package.
