Summary

CVE-2012-5054 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Adobe Flash Player. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique LSA Secrets (T1003.004); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is an integer overflow, identified as CWE-190, in the copyRawDataTo method of the Matrix3D class within Adobe Flash Player versions prior to 11.4.402.265. This flaw resides in the client-side multimedia component responsible for handling 3D matrix transformations and raw data operations.

Remote attackers can exploit the issue by supplying malformed arguments to the affected method, typically through a malicious web page or Flash content that triggers the overflow. Successful exploitation grants the ability to execute arbitrary code on the target system, with the CVSS vector indicating network attack vector, low complexity, no required privileges, and required user interaction, resulting in high impact to confidentiality, integrity, and availability.

Adobe addressed the flaw in security bulletin APSB12-19, which provides patched Flash Player builds and recommends immediate upgrade to version 11.4.402.265 or later. Public exploit code demonstrating the integer overflow and code execution path has been published via repositories such as PacketStorm.
