========================================================================== Ubuntu Security Notice USN-3318-1 June 13, 2017
gnutls26, gnutls28 vulnerabilities ==========================================================================
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.
