Adobe has advised immediate action on patches released this week for a number of its products, which address vulnerabilities that can cause crashes and allow attackers to take control of affected computers.
It yesterday released updates to its Flash, AIR, Reader and Acrobat products, as well as for earlier versions on Windows and Macintosh (and Linux, for Flash) operating systems.
The Flash and AIR updates resolve vulnerabilities that could be used to bypass Flash Player security protections, according to the company.
They also resolve an address leak issue that could "defeat memory address layout randomisation."
The Reader and Acrobat patches address memory corruption flaws that could lead to code execution, and resolve a "use-after-free" vulnerability that could also lead to code execution.
The company considers most of these vulnerabilities to be critical, meaning the exploits are actively being targeted and should be patched immediately.
