CVE-2009-4124
Heap-based buffer overflow in the rb_str_justify function in string.c in Ruby 1.9.1 before 1.9.1-p376 allows context-dependent attackers to execute arbitrary code via unspecified vectors involving (1) String#ljust, (2) String#center, or (3) String#rjust.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
