CVE-2012-4163
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Flash Player before 10.3.183.23 and 11.x before 11.4.402.265 on Windows and Mac OS X, before 10.3.183.23 and 11.x before 11.2.202.238 on Linux, before 11.1.111.16 on Android 2.x and 3.x, and before 11.1.115.17 on Android 4.x; Adobe AIR before 3.4.0.2540; and Adobe AIR SDK before 3.4.0.2540 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2012-4164 and CVE-2012-4165.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisThe program reads or writes outside the bounds of an allocated buffer, corrupting adjacent memory. With crafted input an attacker can overwrite control data and, with effort, redirect execution to their own code. Remediation ranges from bounds checking and safe library functions to compiler mitigations, usually alongside a careful audit of the surrounding code.
