Some vulnerabilities have been reported in Opera, which can be exploited by malicious people to conduct cross-site scripting attacks, disclose sensitive information, or to bypass certain security restrictions.

1) A security issue is caused due to a design error when handling input to file form fields, which can potentially be exploited to trick a user into uploading arbitrary files.

This is related to #3 in:
SA28758

2) An error within the handling of custom comments in image properties can be exploited to execute arbitrary script code in the wrong security context when comments of a malicious image are displayed.

3) An error in the handling of attribute values when importing XML into a document can be exploited to bypass filters and conduct cross-site scripting attacks if these values are used as document content.

The vulnerabilities are reported in versions prior to 9.26.

Solution
Update to version 9.26.
