Vulnerabilities

In OCaml opam before 2.5.1, a .install field containing a destination filepath can use ../ to reach a parent directory.

In OCaml through 4.14.3, Bigarray.reshape allows an integer overflow, and resultant reading of arbitrary memory, when untrusted data is processed.

In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization (runtime/intern.c) enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock() function, which performs unbounded memcpy() operations using attacker-controlled lengths from crafted Marshal data.

The caml_ba_deserialize function in byterun/bigarray.c in the standard library in OCaml 4.06.0 has an integer overflow which, in situations where marshalled data is accepted from an untrusted source, allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a crafted object.

batteriesConfig.mlp in OCaml Batteries Included (aka ocaml-batteries) 2.6 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL.

OCaml compiler allows attackers to have unspecified impact via unknown vectors, a similar issue to CVE-2017-9772 "but with much less impact."

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.
