Summary

CVE-2015-5119 is a critical-severity Use After Free (CWE-416) vulnerability in Adobe Flash Player. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 0.1% 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.

CVE-2015-5119 is a use-after-free vulnerability (CWE-416) in the ByteArray class within Adobe Flash Player's ActionScript 3 implementation. It affects versions 13.x up to 13.0.0.296, 14.x up to 18.0.0.194 on Windows and OS X, and 11.x up to 11.2.202.468 on Linux, enabling memory corruption when specially crafted Flash content overrides a valueOf function.

Remote attackers can exploit the flaw by delivering malicious Flash content, such as through a web browser or document, to achieve arbitrary code execution or a denial of service without requiring authentication or user interaction beyond viewing the content. The vulnerability was actively exploited in the wild during July 2015.

Advisories from openSUSE and related distributions reference updates to address the issue in Flash Player, while public reporting notes the availability of proof-of-concept code tied to the Hacking Team leak highlighting multiple unpatched Flash weaknesses. The flaw carries a CVSS 3.1 base score of 9.8, reflecting its network-exposable impact on confidentiality, integrity, and availability.
