Technical summary

dbcve analysis · high confidence

Use-after-free vulnerability in Adobe Flash Player and Adobe AIR allows remote attackers to execute arbitrary code via unspecified vectors. The vulnerability stems from improper memory management where memory is accessed after being freed, potentially leading to code execution.

MitigationUpdate Adobe Flash Player to version 13.0.0.302/18.0.0.203 (Windows/OS X) or 11.2.202.481 (Linux), and Adobe AIR to 18.0.0.180 or later. Prioritize critical systems given CVSS 10 severity.

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.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
