CVE-2017-5335
The stream reading functions in lib/opencdk/read-packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
