Problem 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).
