Detail

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

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

OpenSSL could be made to expose sensitive information over the network.

Software Description: - openssl1.0: Secure Socket Layer (SSL) cryptographic library and tools - openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

Juraj Somorovsky, Robert Merget, and Nimrod Aviram discovered that certain applications incorrectly used OpenSSL and could be exposed to a padding oracle attack. A remote attacker could possibly use this issue to decrypt data.

Update instructions:

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

Ubuntu 18.10:
libssl1.0.0 1.0.2n-1ubuntu6.2

Ubuntu 18.04 LTS:
libssl1.0.0 1.0.2n-1ubuntu5.3

Ubuntu 16.04 LTS:
libssl1.0.0 1.0.2g-1ubuntu4.15

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