Mandriva Linux Security Advisory : openvpn (MDVSA-2013:167)

low Nessus Plugin ID 66614

Language:

Synopsis

The remote Mandriva Linux host is missing a security update.

Description

Updated openvpn package fixes security vulnerability :

OpenVPN 2.3.0 and earlier running in UDP mode are subject to chosen ciphertext injection due to a non-constant-time HMAC comparison function. Plaintext recovery may be possible using a padding oracle attack on the CBC mode cipher implementation of the crypto library, optimistically at a rate of about one character per 3 hours. PolarSSL seems vulnerable to such an attack; the vulnerability of OpenSSL has not been verified or tested (CVE-2013-2061).

Solution

Update the affected openvpn package.
