Description
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."
Affected configurations
• gnupg gnupg (< 1.4.19)
• gnupg gnupg (>= 2.0 < 2.0.27)
• gnupg gnupg (>= 2.1.0 < 2.1.2)
• canonical ubuntu linux 10.04
• canonical ubuntu linux 12.04
• canonical ubuntu linux 14.04
• canonical ubuntu linux 14.10
