HIGH Summary
The MP4_ReadBox_String function in modules/demux/mp4/libmp4.c in VideoLAN VLC media player before 2.1.6 performs an incorrect cast operation from a 64-bit integer to a 32-bit integer, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a large box size.

NASL family Debian Local Security Checks NASL id DEBIAN_DSA-3150.NASL description Fabian Yamaguchi discovered multiple vulnerabilities in VLC, a multimedia player and streamer : - CVE-2014-9626 The MP4 demuxer, when parsing string boxes, did not properly check the length of the box, leading to a possible integer underflow when using this length value in a call to memcpy(). This could allow remote attackers to cause a denial of service (crash) or arbitrary code execution via crafted MP4 files. - CVE-2014-9627 The MP4 demuxer, when parsing string boxes, did not properly check that the conversion of the box length from 64bit integer to 32bit integer on 32bit platforms did not cause a truncation, leading to a possible buffer overflow. This could allow remote attackers to cause a denial of service (crash) or arbitrary code execution via crafted MP4 files. - CVE-2014-9628 The MP4 demuxer, when parsing string boxes, did not properly check the length of the box, leading to a possible buffer overflow. This could allow remote attackers to cause a denial of service (crash) or arbitrary code execution via crafted MP4 files. - CVE-2014-9629 The Dirac and Schroedinger encoders did not properly check for an integer overflow on 32bit platforms, leading to a possible buffer overflow. This could allow remote attackers to cause a denial of service (crash) or arbitrary code execution. last seen 2020-03-17 modified 2015-02-03 plugin id 81130 published 2015-02-03 reporter This script is Copyright (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/81130 title Debian DSA-3150-1 : vlc - security update NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201603-08.NASL description The remote host is affected by the vulnerability described in GLSA-201603-08 (VLC: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in VLC.
