CVE-2015-1606
The keyring DB in GnuPG before 2.1.2 does not properly handle invalid packets, which allows remote attackers to cause a denial of service (invalid read and use-after-free) via a crafted keyring file.
Does this matter?
Lower severity and a low EPSS score (1.92%). Track it; it rarely justifies an emergency change on its own.
