Adobe Flash Player versions prior to specific patches contain a critical integer handling vulnerability that affects multiple operating systems and platforms. This vulnerability stems from improper integer management within the Flash Player runtime environment, creating potential pathways for information disclosure attacks. The flaw exists across Windows, Mac OS X, Linux, and Solaris platforms for older versions, while Android versions 2.x, 3.x, and 4.x are also impacted by this weakness. The vulnerability falls under the category of improper integer handling as classified by CWE-190, which specifically addresses integer overflow and underflow conditions that can lead to unexpected behavior in software applications.
The technical implementation of this vulnerability allows attackers to manipulate integer values in ways that bypass normal security boundaries within the Flash Player environment. When Flash Player processes integer values incorrectly, it can lead to memory corruption or information leakage that exposes sensitive data. Attackers can exploit this weakness through unspecified vectors that likely involve crafted Flash content or malicious web pages that trigger the vulnerable integer handling code paths. This type of vulnerability aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as attackers may leverage Flash content to execute malicious code that exploits these integer handling flaws.
The operational impact of this vulnerability extends across multiple device types and operating systems, making it particularly dangerous for organizations with diverse computing environments. Users running affected Flash Player versions face potential exposure to information disclosure attacks that could reveal system memory contents, user credentials, or other sensitive data. The vulnerability affects not only desktop operating systems but also mobile platforms including Android devices, amplifying the attack surface significantly. Organizations that rely on Flash Player for web content delivery or multimedia applications are particularly vulnerable since the exploit can occur through normal web browsing activities without requiring user interaction beyond visiting compromised websites.
Security mitigations for this vulnerability primarily involve immediate patching of Flash Player installations across all affected platforms. System administrators should prioritize updating to the patched versions 10.3.183.16 and 11.1.102.63 for Windows, Mac OS X, Linux, and Solaris, while also updating Android versions to 11.1.111.7 for 2.x and 3.x devices and 11.1.115.7 for 4.x devices. Organizations should consider implementing network-based security controls such as web application firewalls and content filtering to prevent access to malicious Flash content. Additionally, disabling Flash Player in web browsers where possible provides an effective defense-in-depth strategy, as the vulnerability requires Flash Player to be present in the execution environment to be exploited. Regular security assessments and monitoring for unauthorized Flash Player installations should be implemented to ensure complete remediation across enterprise environments.
