An issue was discovered in the function mark_beginning_as_normal in nfa.c in flex 2.6.4. There is a stack exhaustion problem caused by the mark_beginning_as_normal function making recursive calls to itself in certain scenarios involving lots of ‘*’ characters. Remote attackers could leverage this vulnerability to cause a denial-of-service.
