Description

The VEGAOpBitmap::AddLine function in Opera before 10.61 does not properly initialize memory during processing of the SIZE attribute of a SELECT element, which allows remote attackers to trigger an invalid memory write operation, and consequently cause a denial of service (application crash) or possibly execute arbitrary code, via a large integer attribute value.

Affected products

Opera Browser: through 10.60; 5.0, 5.0-beta2, 5.0-beta3, 5.0-beta4, 5.0-beta5, 5.0-beta6 (+101)
