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:10 relevant fixed versions and status.

kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and "memcpy with overlapping ranges."
