caml-light <= 0.75 uses mktemp() insecurely, and also does unsafe things in /tmp during make install.

OCaml 3.12.1 and earlier computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.

Multiple integer overflows in tiffread.c in CamlImages 2.2 might allow remote attackers to execute arbitrary code via TIFF images containing large width and height values that trigger heap-based buffer overflows.
