RHEL 7 : ocaml (RHSA-2016:1296)

critical Nessus Plugin ID 91804

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

An update for ocaml is now available for Red Hat Enterprise Linux 7.

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) :

* 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 (specifically, a bit below 2^64), causing a buffer overflow. Further, arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak. (CVE-2015-8869)

Solution

Update the affected packages.
