Summary

CVE-2014-9163 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Adobe Flash Player. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique /etc/passwd and /etc/shadow (T1003.008); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

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

CVE-2014-9163 is a stack-based buffer overflow vulnerability, tracked under CWE-121, that affects Adobe Flash Player versions prior to 13.0.0.259, 14.x and 15.x prior to 15.0.0.246 on Windows and OS X, and prior to 11.2.202.425 on Linux. The flaw resides in the Flash Player component and carries a CVSS 3.1 score of 7.8, reflecting local attack vector, low attack complexity, required user interaction, and high impact on confidentiality, integrity, and availability.

An attacker can exploit the issue by supplying specially crafted content that triggers the overflow, resulting in arbitrary code execution on the affected system. The vulnerability was observed being exploited in the wild in December 2014, with the attack path relying on local access and user interaction such as opening a malicious file or visiting a compromised page that invokes Flash.

Adobe addressed the flaw in security bulletin APSB14-27, which details the updated Flash Player releases that remediate the buffer overflow. The vulnerability is also catalogued in CISA's Known Exploited Vulnerabilities list, confirming active exploitation and underscoring the need for immediate application of the vendor patches on all supported platforms.
