Multiple vulnerabilities have been identified in Opera, which could be exploited by attackers to gain knowledge of sensitive information or execute arbitrary scripts.
The first issue is caused by an error when handling file input data, which could be exploited by malicious websites to trick a user into uploading arbitrary files from an affected system to a remote location.
The second vulnerability is caused by an input validation error when processing comments in image properties, which could be exploited to execute malicious script in the wrong security context.
The third issue is caused by a design where certain attribute values are not correctly presented to the DOM when XML is imported into a document, which could be exploited to bypass sanitization filters and execute malicious scripts.
