A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in p11-kit 0.23.6 through 0.23.21. A heap-based buffer overflow has been discovered in the RPC protocol used by p11-kit server/remote commands and the client library.
