Apple Security Update for Quicktime

Number: AV14-086
Date: 24 October 2014

Purpose

Apple has released updates for QuickTime 7.7.6 software running under Windows to correct four (4) vulnerabilities. Successful exploitation of these vulnerabilities could lead to denial of service or the execution of malicious code.

Assessment

Users playing maliciously crafted movie files may lead to unexpected application termination or arbitrary code execution as a result of memory corruption issues existing in the handling of RLE encoded movie files and the 'mvhd' atoms.

Users playing maliciously crafted MIDI or m4a files may lead to unexpected application termination or arbitrary code execution as a result of buffer overflows existing in the handling of these files.

In all instances, this issue was addressed through improved bounds checking.

Affected products: Windows 7, Vista, XP SP2

CVE References: CVE-2014-1391, CVE-2014-4979, CVE-4350.

Suggested Action

CCIRC recommends that owner/operators test and deploy the vendor released updates or workarounds to affected platforms referred to in Apple Support Article HT6493.
