Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

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.
