NOTE: it was later reported that 10.00 Beta 3 Build 1699 is also affected. | 4.3 |
|||
| 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. | 6.8 |
|||
| 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." | 6.8 |
|||
| Opera executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI.

|||
| Opera before 9.61 does not properly block scripts during preview of a news feed, which allows remote attackers to create arbitrary new feed subscriptions and read the contents of arbitrary feeds. | 5.8 |

HIGH |
||
| Opera before 9.52, when rendering an http page that has loaded an https page into a frame, displays a padlock icon and offers a security information dialog reporting a secure connection, which might allow remote attackers to trick a user into performing unsafe actions on the http page. | 5 |

NOTE: this is similar to CVE-2007-5232. | 2.6 |
|||
| Opera before 9.23 allows remote attackers to execute arbitrary code via crafted Javascript that triggers a "virtual function call on an invalid pointer." | 9.3 |

|||
| Opera 7.54 and earlier does not properly validate base64 encoded binary data in a data: (RFC 2397) URL, which causes the URL to be obscured in a download dialog, which may allow remote attackers to trick users into executing arbitrary code. | 5 |

|||
| Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces. | 5 |
|||
| Argument injection vulnerability in Opera before 7.50 does not properly filter "-" characters that begin a hostname in a telnet URI, which allows remote attackers to insert options to the resulting command line and overwrite arbitrary files via (1) the "-f" option on Windows XP or (2) the "-n" option on Linux. | 2.6 |
|||
| Opera allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Opera to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application. | 7.5 |
