More information:

Ulf Härnhammar discovered a buffer overflow in lynx, a text-mode browser for the WWW that can be remotely exploited. During the handling of Asian characters when connecting to an NNTP server lynx can be tricked to write past the boundary of a buffer which can lead to the execution of arbitrary code.

For the old stable distribution (woody) this problem has been fixed in version 2.8.4.1b-3.2.

For the stable distribution (sarge) this problem has been fixed in version 2.8.5-2sarge1 of lynx.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your lynx-ssl package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
