Package : lynx-ssl Vulnerability : several Problem type : remote Debian-specific: no CVE IDs : CVE-2004-1617 CAN-2005-3120 BugTraq ID : 11443 Debian Bug : 296340
Several vulnerabilities have been discoverd in lynx, the popular text-mode WWW browser. The Common Vulnerabilities and Exposures Project identifies the following vulnerabilities:
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.
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.
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.
