Debian DLA-466-1 : ocaml security update

critical Nessus Plugin ID 91051

Language:

Synopsis

The remote Debian host is missing a security update.

Description

OCaml versions 4.02.3 and earlier have a runtime bug that, on 64-bit platforms, causes sizes arguments to an internal memmove call to be sign-extended from 32 to 64-bits before being passed to the memmove function. This leads arguments between 2GiB and 4GiB to be interpreted as larger than they are (specifically, a bit below 2^64), causing a buffer overflow. Arguments between 4GiB and 6GiB are interpreted as 4GiB smaller than they should be, causing a possible information leak.A

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
