Summary
CVE-2015-3043 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Adobe Flash Player. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 0.5% 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.
Adobe Flash Player versions before 13.0.0.281, 14.x through 17.x before 17.0.0.169 on Windows and OS X, and before 11.2.202.457 on Linux are affected by a memory corruption vulnerability tracked as CVE-2015-3043. The flaw, assigned CWE-787, permits arbitrary code execution or denial of service through unspecified vectors and carries a CVSS 3.1 base score of 9.8. It is distinct from multiple other Flash vulnerabilities disclosed around the same period.
Remote attackers can exploit the issue without authentication or user interaction beyond loading crafted content, enabling full system compromise or service disruption. The vulnerability was actively exploited in the wild during April 2015.
Security advisories from OpenSUSE and Red Hat direct administrators to apply vendor-supplied updates that address the flaw in affected Flash Player releases. These updates are distributed through standard package management channels for the respective Linux distributions.
The issue saw confirmed real-world exploitation shortly after disclosure, underscoring the urgency of patching internet-facing systems that still run the vulnerable plugin.
