Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in OpenSSL.

Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

David Benjamin discovered that OpenSSL did not correctly prevent buggy applications that ignore handshake errors from subsequently calling certain functions. (CVE-2017-3737)

It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery multiplication procedure. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2017-3738)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 17.10:
libssl1.0.0 1.0.2g-1ubuntu13.3

Ubuntu 17.04:
libssl1.0.0 1.0.2g-1ubuntu11.4

Ubuntu 16.04 LTS:
libssl1.0.0 1.0.2g-1ubuntu4.10

After a standard system update you need to reboot your computer to make all the necessary changes.
