Cisco and Adobe have issued updates to address security vulnerabilities in the Flash web tool and IOS networking platform.
Adobe's update addresses a pair of critical vulnerabilities in Flash.
If exploited, the flaws could allow an attacker to remotely execute code on Windows, OS X and Linux systems.
The company has released fixes for all three versions of the Adobe Flash Player and Adobe AIR tools. Users can obtain the patch through the Adobe update tool or through the company's download site.
Cisco, meanwhile, has issued a security update to address eight flaws in its IOS networking appliance software platform.
The company said that the update will address vulnerabilities in IOS which could allow an attacker to bypass firewall protections and create denial of service errors which could disrupt traffic in vulnerable devices.
Among the fixes are updates for the Zone-Based Firewall platform and the Smart Install platform which could allow for denial of service attacks. Other patches in the update address denial of service flaws in the IOS RSVP and Reverse SSH platforms.
The update will also patch a flaw which could allow attackers to exploit a hole in the IOS remote authentication system, potentially leaving HTTP and HTTPS servers vulnerable to remote takeover attacks.
Other patches in the update include fixes for denial of service vulnerabilities in a number of components designed to optimise traffic on the platform, including the Wide Area Application Services and Measurement, Aggregation and Correlation Engine.
The company said administrators can obtain an update to address the vulnerabilities through its service provider partners or manually downloaded from its website. The company is advising firms to check for possible compatibility issues prior to deployment.
