CVE-2015-1607 (GCVE-0-2015-1607)

Vulnerability from cvelistv5 – Published: 2019-11-20 18:30 – Updated: 2024-08-06 04:47

Summary

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."

Severity ?
