CVE-2015-8972
Stack-based buffer overflow in the ValidateMove function in frontend/move.cc in GNU Chess (aka gnuchess) before 6.2.4 might allow context-dependent attackers to execute arbitrary code via a large input, as demonstrated when in UCI mode.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
