Opera plugs security holes; adds ASLR, DEP support
The Opera 9.64 upgrade also adds support for DEP (Data Execution Prevention) and ASLR (Address Space Layout Randomization), two anti-exploitation mechanisms that helps to limit the damage from malware attacks on the Windows platform.
Opera has only released details on one of the three security vulnerabilities, which was discovered and reported by Google’s Tavis Ormandy.
- Specially crafted JPEG images can cause Opera to corrupt memory and crash. Successful exploitation can lead to execution of arbitrary code.
Opera said the update also fixes an issue where plug-ins could be used to allow cross domain scripting and a third “moderately severe” issue that remains a mystery.
“Details will be disclosed at a later date,” the company said.
