Catching Safari up to Internet Explorer, Firefox, and Chrome, Adobe Systems has put its Flash Player plug-in into a sandbox for better security protection on Apple's browser, too.
"With this week's release of Safari in OS X Mavericks, Flash Player will now be protected by an OS X App Sandbox," Adobe platform security strategist Peleus Uhley said Wednesday in a blog post.
Sandboxing restricts the privileges that software gets, for example prohibiting it from writing to a storage device or tampering with data in memory held by another program. Such limits make it harder for malware authors to extend an attack from the browser to a position of more power.
"Safari users on OS X Mavericks can view Flash Player content while benefiting from these added security protections," Uhley said.
