========================================================================== Ubuntu Security Notice USN-3475-1 November 06, 2017
openssl vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in OpenSSL.
Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools
Details:
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. (CVE-2017-3735)
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. (CVE-2017-3736)
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-1ubuntu13.2
Ubuntu 17.04: libssl1.0.0 1.0.2g-1ubuntu11.3
Ubuntu 16.04 LTS: libssl1.0.0 1.0.2g-1ubuntu4.9
Ubuntu 14.04 LTS: libssl1.0.0 1.0.1f-1ubuntu2.23
After a standard system update you need to reboot your computer to make all the necessary changes.
