Multiple vulnerabilities were discovered in Opera, allowing for the execution of arbitrary code and cross domain scripting.

2.  Impact Information


Opera is a fast Web browser that is available free of charge.


David Bloom reported two vulnerabilities where plug-ins (CVE-2007-6520) and Rich text editing (CVE-2007-6522) could be used to allow cross domain scripting. Alexander Klink (Cynops GmbH) discovered an issue with TLS certificates (CVE-2007-6521). Gynvael Coldwind reported that bitmaps might reveal random data from memory (CVE-2007-6524).


A remote attacker could exploit these vulnerabilities, possibly leading to the execution of arbitrary code and cross domain scripting.

3.  Resolution Information


There is no known workaround at this time.


All Opera users should upgrade to the latest version:

Code Listing 3.1: Resolution
