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."

Security readout for executives and security teams

CVE-2015-1607 is a GnuPG denial-of-service flaw. Older GnuPG versions can crash when handling a specially crafted keyring file. The business risk is disruption to systems that automatically process untrusted keys, not data theft or code execution based on the supplied sources. Exposure is mainly legacy systems running affected GnuPG versions, especially mail, package, CI, automation, or key-management workflows that import keyring files from external or low-trust sources. Treat as a targeted legacy cleanup item. Prioritize systems that process third-party keys automatically, because a crash could interrupt security, package, or mail workflows. Mitigation focus: Upgrade GnuPG to 1.4.19, 2.0.27, 2.1.2, or later as applicable.; Apply operating-system vendor security updates for GnuPG packages.; Inventory automated workflows that import or parse externally supplied keyrings..
