MGASA-2017-0372 Updated openvpn packages fix security vulnerability

The bounds check in readkey was performed after using the value, instead of before. If 'key-method 1' is used, this allowed an attacker to send a malformed packet to trigger a stack buffer overflow. Note that 'key-method 1' has been replaced by 'key method 2' as the default in OpenVPN 2.0...

OpenVPN read_key Stack Based Buffer Overflow (CVE-2017-12166)

A stack-based buffer overflow vulnerability exists in OpenVPN. The vulnerability is due to a lack of bounds check on the length of key and HMAC lengths provided by the client. A remote, unauthenticated attacker can exploit this vulnerability by sending a crafted PCONTROLV1 message to a target...

OpenVPN 'read_key()' function buffer overflow vulnerability

OpenVPN is an open source VPN program. A buffer overflow vulnerability exists in the OpenVPN 'readkey' function, which allows remote attackers to exploit the vulnerability by submitting a special request that could crash the application or execute arbitrary code...
