Description

Opera before 10.53 on Windows and Mac OS X does not properly handle a series of document modifications that occur asynchronously, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop, leading to attempted use of uninitialized memory. NOTE: this might overlap CVE-2006-6955.

Affected products

Opera Browser: through 10.52; 5.0, 5.0-beta2, 5.0-beta3, 5.0-beta4, 5.0-beta5, 5.0-beta6 (+84)
