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.");
