Ubuntu Security Notice 3611-2 - USN-3611-1 fixed a vulnerability in OpenSSL. This update provides the corresponding update for Ubuntu 12.04 ESM. It was discovered that OpenSSL incorrectly parsed the IPAddressFamily extension in X.509 certificates, resulting in an erroneous display of the certificate in text format. Various other issues were also addressed.

Ubuntu Security Notice 3475-1 - It was discovered that OpenSSL incorrectly parsed the IPAddressFamily extension in X.509 certificates, resulting in an erroneous display of the certificate in text format. It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied to Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04. Various other issues were also addressed.

OpenSSL Security Advisory 20171102 - There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. Other issues were also addressed.

OpenSSL Security Advisory 20170828 - 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.
