NASL family Windows NASL id VLC_3_0_8.NASL description The version of VLC media player installed on the remote Windows host is prior to 3.0.8. It is, therefore, affected by multiple vulnerabilities: - An integer underflow condition exists in the modules/demux/mp4/mp4.c component of VLC Player. An unauthenticated, remote attacker can exploit this, by supplying a crafted mp4 file, to cause a denial of service condition or the execution of arbitrary code (CVE-2019-13602). - A heap-based buffer overflow condition exists in the modules/codec/avcodec/video.c component of VLC Player due to improper sanitization of the width and height values. A remote attacker can exploit this, by supplying a specially crafted video file, to cause a denial of service condition or the execution of arbitrary code (CVE-2019-13962). - A NULL pointer de-reference flaw exists in the ASF Demuxer component of VLC Player. An unauthenticated, remote attacker can exploit this, by supplying crafted input, to cause a denial of service condition when the application attempts to read or write memory with a NULL pointer (CVE-2019-14534). last seen 2020-05-09 modified 2019-08-23 plugin id 128080 published 2019-08-23 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/128080 title VLC < 3.0.8 Multiple Vulnerabilities NASL family Debian Local Security Checks NASL id DEBIAN_DSA-4504.NASL description Multiple security issues were discovered in the VLC media player, which could result in the execution of arbitrary code or denial of service if a malformed file/stream is processed. last seen 2020-06-01 modified 2020-06-02 plugin id 128066 published 2019-08-22 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/128066 title Debian DSA-4504-1 : vlc - security update NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201909-02.NASL description The remote host is affected by the vulnerability described in GLSA-201909-02 (VLC: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in VLC.
