The remote host is missing an update to netrik announced via advisory DSA 1251-1. It has been discovered that netrik, a text mode WWW browser with vi like keybindings, doesn't properly sanitize temporary filenames when editing textareas which could allow attackers to execute arbitrary commands via shell metacharacters.

For the stable distribution (sarge), this problem has been fixed in version 1.15.4-1sarge1. For the upcoming stable distribution (etch) this problem has been fixed in version 1.15.3-1.1. For the unstable distribution (sid) this problem has been fixed in version 1.15.3-1.1. We recommend that you upgrade your netrik package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201251-1
