Posted by Benjamin D. Thomas   
Kalle Olavi Niemitalo discovered that if elinks makes a POST request to an HTTPS URL through a proxy, information may be sent in clear-text between elinks and the proxy. Attackers with access to the network could steal sensitive information (such as passwords).
 
Ubuntu: Linux kernel vulnerabilities  24 September 2007 
Posted by Benjamin D. Thomas
