Apple and Adobe have joined Microsoft in releasing security updates on a busy day for IT administrators.
The companies issued fixes designed to protect against critical vulnerabilities including remote code execution flaws.
The Adobe update addresses vulnerabilities in the Shockwave Player for Windows and Mac OS X systems. The company advises users to install Shockwave Player version 220.127.116.113 to protect against attack.
Adobe classifies the update as 'critical', warning that the flaw could allow an attacker to execute code on a targeted system.
The Apple update, meanwhile, fixes 17 vulnerabilities in Java for Mac OS X 10.6 and 10.7 systems, some of which could allow an attacker to execute code outside the secure Java sandbox.
The updates follow Microsoft's November Patch Tuesday security release, which includes fixes for a critical vulnerability in the Windows 7 and Windows Vista TCP/IP component.
Vulnerabilities in third-party components such as Shockwave and Java have been a growing concern for businesses, as patches can often be missed or overlooked by users and administrators.
Security firms have noted that Java poses a particular risk, as the need for extensive testing by administrators can often leave computers exposed to vulnerabilities for extended periods.
