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 · unedited
Buffer overflow in Adobe Flash Player before 10.3.183.29 and 11.x before 11.4.402.287 on Windows and Mac OS X, before 10.3.183.29 and 11.x before 11.2.202.243 on Linux, before 11.1.111.19 on Android 2.x and 3.x, and before 11.1.115.20 on Android 4.x; Adobe AIR before 3.4.0.2710; and Adobe AIR SDK before 3.4.0.2710 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than other Flash Player buffer overflow CVEs listed in APSB12-22.

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.
