Calendar Grey March 21, 2017
Scroller Redhat
This crucial security notice outlines an ocaml patch for Red Hat Enterprise Linux 6 that mitigates a potential buffer overflow vulnerability.
An update for ocaml is now available for Red Hat Enterprise Linux 6

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
