Ubuntu Security Notice 3437-1 - Radek Micek discovered that OCaml incorrectly handled sign extensions. A remote attacker could use this issue to cause applications using OCaml to crash, to possibly obtain sensitive information, or to possibly execute arbitrary code.
4fc5d9593a2242ea01f057e6a7a61b13baf8fe1bbacd8ed9d2123f3ac61c271dRed Hat Security Advisory 2017-0565-01 - OCaml is a high-level, strongly-typed, functional, and object-oriented programming language from the ML family of languages. The ocaml packages contain two batch compilers, an interactive top level system, parsing tools, a replay debugger, a documentation generator, and a comprehensive library. Security Fix: An integer conversion flaw was found in the way OCaml's String handled its length. Certain operations on an excessively long String could trigger a buffer overflow or result in an information leak.

Security Fix: An integer conversion flaw was found in the way OCaml's String handled its length. Certain operations on an excessively long String could trigger a buffer overflow or result in an information leak. Note: The libguestfs packages in this advisory were rebuilt with a fixed version of OCaml to address this issue.

Virt-p2v is a tool for conversion of a physical server to a virtual guest. The following packages have been upgraded to a newer upstream version: libguestfs, virt-p2v. Security Fix: An integer conversion flaw was found in the way OCaml's String handled its length. Certain operations on an excessively long String could trigger a buffer overflow or result in an information leak.

The ocaml packages contain two batch compilers, an interactive top level system, parsing tools, a replay debugger, a documentation generator, and a comprehensive library. Security Fix: OCaml versions 4.02.3 and earlier have a runtime bug that, on 64-bit platforms, causes size arguments to internal memmove calls to be sign-extended from 32- to 64-bits before being passed to the memmove function. This leads to arguments between 2GiB and 4GiB being interpreted as larger than they are, causing a buffer overflow. Further, arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak.
