Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 : openssl vulnerability (USN-1428-1)

high Nessus Plugin ID 58873
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

It was discovered that the fix for CVE-2012-2110 was incomplete for OpenSSL 0.9.8. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. Ubuntu 11.10 was not affected by this issue. (CVE-2012-2131)

The original upstream fix for CVE-2012-2110 would cause BUF_MEM_grow_clean() to sometimes return the wrong error condition.
This update fixes the problem.

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 libssl0.9.8 and / or libssl1.0.0 packages.
