high Nessus Plugin ID 92892

Synopsis

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

Description

Due to insufficient sanitization of the input patch stream, it is possible for a patch file to cause patch(1) to pass certain ed(1) scripts to the ed(1) editor, which would run commands. Impact : This issue could be exploited to execute arbitrary commands as the user invoking patch(1) against a specially crafted patch file, which could be leveraged to obtain elevated privileges.

Solution

Update the affected package.
