CVE-2005-1139 1 Opera 1 Opera Browser 2024-11-20 7.5 HIGH N/A
Opera 8 Beta 3, when using first-generation vetted digital certificates, displays the Organizational information of an SSL certificate, which is easily spoofed and can facilitate phishing attacks.
CVE-2005-0457 1 Opera 1 Opera Browser 2024-11-20 7.2 HIGH N/A
Opera 7.54 and earlier on Gentoo Linux uses an insecure path for plugins, which could allow local users to gain privileges by inserting malicious libraries into the PORTAGE_TMPDIR (portage) temporary directory.
CVE-2005-0456 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
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.
CVE-2005-0238 4 Gnome, Mozilla, Omnigroup and 1 more 5 Epiphany, Camino, Mozilla and 2 more 2024-11-20 5.0 MEDIUM N/A
The International Domain Name (IDN) support in Epiphany allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
CVE-2005-0235 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
The International Domain Name (IDN) support in Opera 7.54 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
CVE-2005-0233 4 Mozilla, Omnigroup, Opera and 1 more 6 Camino, Firefox, Mozilla and 3 more 2024-11-20 7.5 HIGH N/A
The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5, and Mozilla before 1.7.6 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
CVE-2004-2659 2 Mozilla, Opera 2 Mozilla, Opera Browser 2024-11-20 4.0 MEDIUM N/A
Opera offers an Open button to verify that a user wishes to execute a downloaded file, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking Open via a request for a different mouse or keyboard action very shortly before the Open dialog appears. NOTE: this is a different issue than CVE-2005-2407.
CVE-2004-2570 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
Opera before 7.54 allows remote attackers to modify properties and methods of the location object and execute Javascript to read arbitrary files from the client's local filesystem or display a false URL to the user.
CVE-2004-2491 1 Opera 1 Opera Browser 2024-11-20 2.6 LOW N/A
A race condition in Opera web browser 7.53 Build 3850 causes Opera to fill in the address bar before the page has been loaded, which allows remote attackers to spoof the URL in the address bar via the window.open and location.replace HTML parameters, which facilitates phishing attacks.
CVE-2004-2260 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
Opera Browser 7.23, and other versions before 7.50, updates the address bar as soon as the user clicks a link, which allows remote attackers to redirect to other sites via the onUnload attribute.
CVE-2004-2083 1 Opera 1 Opera Browser 2024-11-20 2.6 LOW N/A
Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."
CVE-2004-1810 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
The Javascript engine in Opera 7.23 allows remote attackers to cause a denial of service (crash) by creating a new Array object with a large size value, then writing into that array.
CVE-2004-1615 1 Opera 1 Opera Browser 2024-11-20 2.6 LOW N/A
Opera allows remote attackers to cause a denial of service (invalid memory reference and application crash) via a web page or HTML email that contains a TBODY tag with a large COL SPAN value, as demonstrated by mangleme.
CVE-2004-1491 4 Gentoo, Kde, Opera and 1 more 4 Linux, Kde, Opera Browser and 1 more 2024-11-20 5.0 MEDIUM N/A

CVE-2004-1490 1 Opera 1 Opera Browser 2024-11-20 2.6 LOW N/A
Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers.
CVE-2004-1489 1 Opera 1 Opera Browser 2024-11-20 2.6 LOW N/A
Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory.
CVE-2004-1201 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
Opera 7.54 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.
CVE-2004-1157 1 Opera 1 Opera Browser 2024-11-20 7.5 HIGH N/A
Opera 7.x up to 7.54, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.
CVE-2004-0872 1 Opera 1 Opera Browser 2024-11-20 5.0 MEDIUM N/A
Opera does not prevent cookies that are sent over an insecure channel (HTTP) from also being sent over a secure channel (HTTPS/SSL) in the same domain, which could allow remote attackers to steal cookies and conduct unauthorized activities, aka "Cross Security Boundary Cookie Injection."
