FreeBSD : ripMIME -- decoding bug allowing content filter bypass (85e19dff-e606-11d8-9b0a-000347a4fa7d)

high Nessus Plugin ID 37039

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

ripMIME may prematurely terminate decoding Base64 encoded messages when it encounters multiple blank lines or other non-standard Base64 constructs. Virus scanning and content filtering tools that use ripMIME may therefore be bypassed.

The ripMIME CHANGELOG file says :

There's viruses going around exploiting the ability to hide the majority of their data in an attachment by using blank lines and other tricks to make scanning systems prematurely terminate their base64 decoding.

Solution

Update the affected package.
