Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178.
Opera before 9.63 does not block unspecified "scripted URLs" during the feed preview, which allows remote attackers to read existing subscriptions and force subscriptions to arbitrary feed URLs.
Cross-site scripting (XSS) vulnerability in Opera before 9.63 allows remote attackers to inject arbitrary web script or HTML via built-in XSLT templates.
Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232.
Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.
