Detail

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

- Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in GnuTLS.

Software Description: - gnutls28: GNU TLS library - gnutls26: GNU TLS library

Details:

Hubert Kario discovered that GnuTLS incorrectly handled decoding a status response TLS extension. A remote attacker could possibly use this issue to cause GnuTLS to crash, resulting in a denial of service. This issue only applied to Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04. (CVE-2017-7507)

It was discovered that GnuTLS incorrectly handled decoding certain OpenPGP certificates. A remote attacker could use this issue to cause GnuTLS to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2017-7869)

Update instructions:

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

Ubuntu 17.04:
libgnutls30 3.5.6-4ubuntu4.1

Ubuntu 16.10:
libgnutls30 3.5.3-5ubuntu1.2

Ubuntu 16.04 LTS:
libgnutls30 3.4.10-4ubuntu1.3

Ubuntu 14.04 LTS:
libgnutls26 2.12.23-12ubuntu2.8

In general, a standard system update will make all the necessary changes.
