CVE-2015-1607

MEDIUM5.5

kbx/keybox-search

Published Nov 20, 2019

Modified 1 years ago

Details

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."
