DATE CVE VULNERABILITY TITLE RISK
2009-09-18 CVE-2008-7245 Resource Management Errors vulnerability in Opera Browser
Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.

opera CWE-399
5.0
2009-09-02 CVE-2009-3048 Improper Input Validation vulnerability in Opera Browser
Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file."
4.3
2009-09-02 CVE-2009-3046 Improper Certificate Validation vulnerability in Opera Browser
Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate.

low complexity
opera CWE-295
7.5
2009-09-02 CVE-2009-3044 Cryptographic Issues vulnerability in Opera Browser
Opera before 10.00 does not properly handle a (1) '\0' character or (2) invalid wildcard character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

2009-08-31 CVE-2009-3013 Cross-Site Scripting vulnerability in Opera Browser
Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header.

2009-07-22 CVE-2009-2577 Resource Management Errors vulnerability in Opera Browser
Opera 9.52 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption, and application hang) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479.

2009-07-07 CVE-2009-2351 Cross-Site Scripting vulnerability in Opera Browser
Opera 9.52 and earlier does not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header, a related issue to CVE-2009-1312.

opera CWE-79
4.3
2009-06-15 CVE-2009-2067 Improper Authentication vulnerability in Opera Browser
Opera detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."

opera CWE-287
6.8
2009-06-15 CVE-2009-2063 Improper Authentication vulnerability in Opera Browser
Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.

opera CWE-287
6.8
2009-06-15 CVE-2009-2059 Improper Authentication vulnerability in Opera Browser
Opera, possibly before 9.25, uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.
