Summary
Security update for openvpn
Notes
Title of the patch
Security update for openvpn
Description of the patch
This update for openvpn fixes the following issues:
- Some parts of the certificate-parsing code did not always clear all allocated
memory. This would have allowed clients to leak a few bytes of memory for
each connection attempt, thereby facilitating a (quite inefficient) DoS
attack on the server. [bsc#1044947, CVE-2017-7521]
- The ASN1 parsing code contained a bug that could have resulted in some
buffers being free()d twice, and this issue could have potentially been
triggered remotely by a VPN peer. [bsc#1044947, CVE-2017-7521]
- If clients used a HTTP proxy with NTLM authentication, a man-in-the-middle
attacker between client and proxy could cause the client to crash or disclose
at most 96 bytes of stack memory. The disclosed stack memory was likely to
contain the proxy password. If the proxy password had not been reused, this
was unlikely to compromise the security of the OpenVPN tunnel itself. Clients
who did not use the --http-proxy option with ntlm2 authentication were not
affected. [bsc#1044947, CVE-2017-7520]
- It was possible to trigger an assertion by sending a malformed IPv6 packet.
That issue could have been abused to remotely shutdown an openvpn server or
client, if IPv6 and --mssfix were enabled and if the IPv6 networks used
inside the VPN were known. [bsc#1044947, CVE-2017-7508]

Summary
Security update for openvpn-openssl1
Notes
Title of the patch
Security update for openvpn-openssl1
Description of the patch
This update for openvpn-openssl1 fixes the following issues:
- Some parts of the certificate-parsing code did not always clear all allocated
memory. This would have allowed clients to leak a few bytes of memory for
each connection attempt, thereby facilitating a (quite inefficient) DoS
attack on the server. [bsc#1044947, CVE-2017-7521]
- The ASN1 parsing code contained a bug that could have resulted in some
buffers being free()d twice, and this issue could have potentially been
triggered remotely by a VPN peer. [bsc#1044947, CVE-2017-7521]
- If clients used a HTTP proxy with NTLM authentication, a man-in-the-middle
attacker between client and proxy could cause the client to crash or disclose
at most 96 bytes of stack memory. The disclosed stack memory was likely to
contain the proxy password. If the proxy password had not been reused, this
was unlikely to compromise the security of the OpenVPN tunnel itself. Clients
who did not use the --http-proxy option with ntlm2 authentication were not
affected. [bsc#1044947, CVE-2017-7520]
- It was possible to trigger an assertion by sending a malformed IPv6 packet.
That issue could have been abused to remotely shutdown an openvpn server or
client, if IPv6 and --mssfix were enabled and if the IPv6 networks used
inside the VPN were known. [bsc#1044947, CVE-2017-7508]
- The installed sample configuration file was updated to comply to FIPS
requirements. [bsc#988522]
- Remedy large latencies on the openVPN server during authentication process.
[bsc#959511]
- Fix potential denial-of-service attacks found during independent audits.
