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).

openvpn-2.2.2-5.3.mga2.i586.rpm
