announced via advisory DSA 1085-1.


Several vulnerabilities have been discoverd in lynx, the popular
text-mode WWW browser.  The Common Vulnerabilities and Exposures
Project identifies the following vulnerabilities:

CVE-2004-1617

Michal Zalewski discovered that lynx is not able to grok invalid
HTML including a TEXTAREA tag with a large COLS value and a large
tag name in an element that is not terminated, and loops forever
trying to render the broken HTML.

CVE-2005-3120

Ulf Härnhammar discovered a buffer overflow 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) these problems have been fixed in
version 2.8.5-2.5woody1.";
