CVE-2008-3196
skeleton.c in yacc does not properly handle reduction of a rule with an empty right hand side, which allows context-dependent attackers to cause an out-of-bounds stack access when the yacc stack pointer points to the end of the stack.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
