Description

An update for ocaml is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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 (a fast bytecode compiler and an optimizing native-code compiler), an interactive top level system, parsing tools (Lex, Yacc, Camlp4), a replay debugger, a documentation generator, and a comprehensive library.

Security Fix(es) :

  • 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. (CVE-2015-8869)

Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.
