lynx security update

CentOS Errata and Security Advisory CESA-2008:0965

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. (CVE-2008-4690)

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. (CVE-2006-7234)

All users of Lynx are advised to upgrade to this updated package, which
contains backported patches correcting these issues.
