Aug 28, 2017, OpenSSL announced the following security advisories: https://www.openssl.org/news/secadv/20170828.txt

Advisory CVEs

  • CVE-2017-3735 - Malformed X.509 IPAddressFamily could cause OOB read (Severity: Low)

If an X.509 certificate has a malformed IPAddressFamily extension, OpenSSL could do a one-byte buffer overread. The most likely result would be an erroneous display of the certificate in text format.

As this is a low severity fix, no release is being made. The fix can be found in the source repository (1.0.2, 1.1.0, and master branches); see https://github.com/openssl/openssl/pull/4276. This bug has been present since 2006.

Please see the security bulletin above for patch, upgrade, or suggested work around information.


xCAT uses OpenSSL for client-server communication but does not ship it.

It is highly recommended to keep your OpenSSL levels up-to-date with the indicated versions in the security bulletins to prevent any potential security threats. Obtain the updated software packages from your Operating system distribution channels.
