Microsoft, Adobe patch critical security flaws
The 15 patches include patches for two vulnerabilities that according to security company Rapid7 are zero day exploits that affect all supported versions of Windows.
The vulnerabilities can result in unauthorised elevation of privilege that could allow attackers to respectively run arbitrary code in kernel mode, and to install programs, view change and delete data, and create new accounts with full user rights.
The vulnerabilities require attackers to have first obtained local access to an affected system, but according to Rapid7, when combined with one of the remote code execution vulnerabilities also patched by Microsoft, could be used to obtain full control of a system as part of an exploit chain.
Microsoft has also issued patches for various software including its Internet Explorer and Edge web browsers, as well as Microsoft Office, Sharepoint and Exchange. These include 32 remote code execution vulnerabilities.
Meanwhile, Adobe has also issued fixes for several products, including Flash, Reader and Shockwave Player.
This includes an update to resolve multiple critical memory corruption vulnerabilities in Shockwave Player that could lead to arbitrary code execution attacks, which was issued on the same day as Adobe officially ended support for the obsolete program.
