gnutls26, gnutls28 vulnerabilities
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)
