Debian Security Advisory DSA-3363-1 email@example.com https://www.debian.org/security/ Luciano Bello September 20, 2015 https://www.debian.org/security/faq
Package : owncloud-client CVE ID : CVE-2015-4456
Johannes Kliemann discovered a vulnerability in ownCloud Desktop Client, the client-side of the ownCloud file sharing services. The vulnerability allows man-in-the-middle attacks in situations where the server is using self-signed certificates and the connection is already established. If the user in the client side manually distrusts the new certificate, the file syncing will continue using the malicious server as valid.
