Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2016-2183)

The vulnerability allows a remote attacker to decrypt transmitted data.

The vulnerability exists due to remote user's ability to control the network and capture long duration 3DES CBC mode encrypted session during which he can see a part of the text. In case of repeated sending the attacker can read the part and reconstruct the whole text.

Successful exploitation of this vulnerability may allow a remote attacker to decode transmitted data. This vulnerability is known as SWEET32.


2) Access control error (CVE-ID: CVE-2016-6329)

The vulnerability allows attackers to gain access to potentially sensitive information.

The vulnerability exists due to capturing of long duration Blowfish CBC mode encrypted TLS session. Repeated sending of communication protocol with parts of the plaintext helps attackers to reconstruct the secret information.

Successful exploitation of this vulnerability may allow a remote attacker to access potentially sensitive data.
