    Published: 16 Jul 2008Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
