Vulnerability CVE-2011-1824
Published: 2011-05-10   Modified: 2012-02-13

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.
