CVE-2015-1606 Open this link in a new tabHow to fix?
Upgrade Debian:9 gnupg2 to version 2.0.26-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gnupg2 package and not the gnupg2 package as distributed by Debian.
See How to fix? for Debian:9 relevant fixed versions and status.
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.
