Ubuntu 13.10 : openssh vulnerability (USN-2014-1)

medium Nessus Plugin ID 70798

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Markus Friedl discovered that OpenSSH incorrectly handled memory when the AES-GCM cipher was used. A remote authenticated attacker could use this issue to execute arbitrary code as their user, possibly bypassing shell or command restrictions.

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 openssh-server package.
