lynx -- remote buffer overflow

Description:

Ulf Härnhammar reports:

When Lynx connects to an NNTP server to fetch information about the available articles in a newsgroup, it will call a function called HTrjis() with the information from certain article headers. The function adds missing ESC characters to certain data, to support Asian character sets. However, it does not check if it writes outside of the char array buf, and that causes a remote stack-based buffer overflow.
