Last modified

CVE-2013-4351 is a vulnerability of currently unknown severity. GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey.. EPSS estimates a 2.52% chance of exploitation in the next 30 days.
