Updated gnupg and gnupg2 packages fix security vulnerabilities:
Hanno Böck discovered that GnuPG incorrectly handled certain malformed keyrings. If a user or automated system were tricked into opening a malformed keyring, a remote attacker could use this issue to cause GnuPG to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2015-1606, CVE-2015-1607).
