Vigil@nce - OpenSSL: memory leak via hostname
March 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can create a memory leak in the hostname extension of
OpenSSL, in order to trigger a denial of service.
Impacted products: OpenSSL
Severity: 2/4
Creation date: 16/03/2015
DESCRIPTION OF THE VULNERABILITY
The OpenSSL library supports the "hostname" TLS extension.
However, the memory allocated to process this extension is never
freed.
An attacker can therefore create a memory leak in the hostname
extension of OpenSSL, in order to trigger a denial of service.
