"Several vulnerabilities have been discovered 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 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."
