FreeBSD : picasm -- buffer overflow vulnerability (8a3ece40-3315-11da-a263-0001020eed82)

medium Nessus Plugin ID 21467

Synopsis

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

Description

Shaun Colley reports :

When generating error and warning messages, picasm copies strings into fixed length buffers without bounds checking.

If an attacker could trick a user into assembling a source file with a malformed 'error' directive, arbitrary code could be executed with the privileges of the user. This could result in full system compromise.

Solution

Update the affected package.
