Adobe has patched seven vulnerabilities in its Flash and Air platforms and one in Reader and Acrobat that is being exploited by attackers.
The vulnerabilities could allow attacker to "take control of affected systems" dubbed critical by the company.
Administrators were urged to apply the updates within three days on Windows, Mac, and Linux platforms.
The updates resolved memory leakage vulnerabilities that could bypass memory address randomisation, a security bypass vulnerability, and a use-after-free flaw leading to code execution.
Adobe issued the lone patch rated critical for Reader and Acrobat platform after it found black hats targeted the flaws in "limited, isolated attacks" against Windows users.
"These updates resolve a sandbox bypass vulnerability that could be exploited to run native code with escalated privileges on Windows," Adobe warned.
The company thanked Kaspersky researchers Costin Raiu and Vitaly Kamluk for reporting the latter vulnerability.
Microsoft also issued nine patches for Internet Explorer; Windows Media Center; One Note; SQL Server, and SharePoint. Redmond warned the browser flaws were under active attack.
The patches followed Microsoft's torpedoing of dodgy outdated Active X and .NET controls. ®
