Description Andrej Nemec 2017-06-26 08:57:44 UTC
Insufficient sanitisation in the OCaml compiler versions 4.04.0 and 4.04.1 allows external code to be executed with raised privilege in binaries marked as setuid, by setting the CAML_CPLUGINS, CAML_NATIVE_CPLUGINS, or CAML_BYTE_CPLUGINS environment variable.
