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 we bbrowser. A buffer overflow will
be 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.
We recommend that you upgrade your w3m packages immediately.
