VLC media player versions 3.0.20 and earlier are affected by a high-severity vulnerability that enables denial of service through an integer overflow. This vulnerability can be exploited using a maliciously crafted MMS stream, potentially leading to a crash of the VLC application or arbitrary code execution with the privileges of the target user. The CVSS score of 8 signifies a critical need for attention from security professionals.
Risk to organizations includes potential disruption of services and exploitation of user privileges, making it imperative for users to patch or upgrade their applications promptly. Given the high exploitability of this vulnerability, organizations should prioritize patching immediately.
As of now, there are no public exploits confirmed, but the nature of the vulnerability indicates a significant risk, especially in environments where VLC is widely used. Organizations must remain vigilant and ensure they are operating on the latest version to mitigate any possible risks.
Given the potential impacts, it is essential for users to take immediate action to secure their systems against this vulnerability.
Vulnerability Details
This vulnerability allows denial of service through an integer overflow triggered by a maliciously crafted MMS stream, leading to a heap-based overflow. The affected product is VLC media player, specifically versions 3.0.20 and earlier.
The CVSS score is 8, categorizing this vulnerability as high severity. The impact on confidentiality, integrity, and availability is rated high, indicating severe implications if exploited.
This vulnerability is classified under CWE-122, which pertains to heap-based buffer overflow issues.
Technical Analysis
The root cause of this vulnerability lies in an integer overflow when processing MMS streams. This issue arises from inadequate input validation, allowing attackers to manipulate memory allocation. The attack vector is network-based, requiring low attack complexity and low privileges, but it necessitates user interaction to initiate the malicious stream.
Exploitation could lead to a complete application crash or arbitrary code execution, significantly impacting the affected user's confidentiality, integrity, and availability. Given the low complexity and necessary user interaction, attackers may find it relatively straightforward to exploit this vulnerability.
Risk & Impact Analysis
The deployment risk associated with this vulnerability is high, particularly for organizations relying on VLC media player for media playback. The blast radius could extend to all users operating vulnerable versions, leading to widespread service disruption.
Organizations should assess their usage of VLC media player and prioritize remediation efforts, especially in environments where multimedia playback is critical. Given the CVSS score of 8, it is essential to address this vulnerability in the next patch cycle.
The low EPSS score indicates a relatively lower likelihood of exploitation in the wild, but organizations should still be cautious due to the potential impacts that could arise from successful exploitation.
