Lynx is a text-based Web browser.
An arbitrary command execution flaw was found in the Lynx "lynxcgi:" URI handler. An attacker could create a web page redirecting to a malicious URL that could execute arbitrary code as the user running Lynx in the non-default "Advanced" user mode. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4690 to this issue.
Note: In these updated lynx packages, Lynx will always prompt users before loading a "lynxcgi:" URI. Additionally, the default lynx.cfg configuration file now marks all "lynxcgi:" URIs as untrusted by default.
A flaw was found in a way Lynx handled ".mailcap" and ".mime.types" configuration files. Files in the browser's current working directory were opened before those in the user's home directory. A local attacker, able to convince a user to run Lynx in a directory under their control, could possibly execute arbitrary commands as the user running Lynx. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-7234 to this issue.
