Debian DSA-081-1 : w3m - Buffer Overflow

high Nessus Plugin ID 14918

Synopsis

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

Description

In SNS Advisory No. 32 a buffer overflow vulnerability has been reported in the routine which parses MIME headers that are returned from web servers. A malicious web server administrator could exploit this and let the client web browser execute arbitrary code.

w3m handles MIME headers included in the request/response message of HTTP communication like any other web browser. A buffer overflow will occur when w3m receives a MIME encoded header with base64 format.

This problem has been fixed by the maintainer in version 0.1.10+0.1.11pre+kokb23-4 of w3m and w3m-ssl (for the SSL-enabled version), both for Debian GNU/Linux 2.2.

Solution

Upgrade the w3m packages immediately.
