DESCRIPTION: Some vulnerabilities have been reported in Opera, which potentially can be exploited by malicious people to compromise a user's system. Successful exploitation of the vulnerabilities may allow execution of arbitrary code. The vulnerabilities are reported in versions prior to 9.27.

1) An error when prompting the user to add a newsfeed can be exploited to cause an invalid memory access via a specially crafted newsfeed source.
2) An error exists in the processing of HTML CANVAS elements. This can be exploited to cause a memory corruption via specially crafted scaled pattern images.

SOLUTION: Update to version 9.27.
