CVE-2016-1019
Published: 07 April 2016
Summary
CVE-2016-1019 is a critical-severity an unspecified weakness vulnerability in Apple Mac Os X. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 1.8% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
The strongest mitigations our analysis identified are NIST 800-53 CM-7 (Least Functionality) and SI-2 (Flaw Remediation).
Deeper analysis
Adobe Flash Player versions 21.0.0.197 and earlier contain an unspecified vulnerability that can be triggered to produce an application crash or potentially allow arbitrary code execution. The flaw carries a CVSS 3.1 base score of 9.8 and is tracked under NVD-CWE-noinfo, indicating insufficient public detail on the underlying weakness.
Remote attackers can exploit the issue over the network without authentication or user interaction, enabling denial-of-service conditions or full code execution on affected systems. The vulnerability was observed being exploited in the wild during April 2016.
Adobe security advisories and corresponding updates from Linux distributions such as openSUSE document the availability of patched Flash Player releases and recommend prompt installation to address the exposure. The in-the-wild exploitation noted at disclosure time underscores the need for rapid remediation in environments still running legacy Flash components.
