Ubuntu 14.04 LTS : rsync vulnerability (USN-2171-1)

high Nessus Plugin ID 73681

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2171-1 advisory.

 Ryan Finnie discovered that the rsync daemon incorrectly handled invalid usernames. A remote attacker could use this issue to cause rsync to consume resources, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected rsync package.
