Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
