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 Harnhammar 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.

For the stable distribution (sarge) these problems have been fixed in version 2.8.6-9sarge1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your lynx-cur package.");
