Ubuntu 5.04 / 5.10 / 6.06 LTS : openssl vulnerability (USN-353-2)

high Nessus Plugin ID 27934
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 one or more security-related patches.

Description

USN-353-1 fixed several vulnerabilities in OpenSSL. However, Mark J Cox noticed that the applied patch for CVE-2006-2940 was flawed. This update corrects that patch.

For reference, this is the relevant part of the original advisory :

Certain types of public key could take disproportionate amounts of time to process. The library now limits the maximum key exponent size to avoid Denial of Service attacks. (CVE-2006-2940).

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.
