CVE-2020-25125

HIGH 7.8EPSS 1.28%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

GnuPG 2.2.21 and 2.2.22 (and Gpg4win 3.1.12) has an array overflow, leading to a crash or possibly unspecified other impact, when a victim imports an attacker's OpenPGP key, and this key has AEAD preferences. The overflow is caused by a g10/key-check.c error. NOTE: GnuPG 2.3.x is unaffected. GnuPG 2.2.23 is a fixed version.
