| CVE-2005-3007 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera before 8.50 allows remote attackers to spoof the content type of files via a filename with a trailing "." (dot), which might allow remote attackers to trick users into processing dangerous content. | ||||
| CVE-2004-1201 | 1 Opera | 1 Opera Browser | 2026-04-16 | 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-2006-3331 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera before 9.0 does not reset the SSL security bar after displaying a download dialog from an SSL-enabled website, which allows remote attackers to spoof a trusted SSL certificate from an untrusted website and facilitates phishing attacks. | ||||
| CVE-2005-1139 | 1 Opera | 1 Opera Browser | 2026-04-16 | 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-2006-3353 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 9 allows remote attackers to cause a denial of service (crash) via a crafted web page that triggers an out-of-bounds memory access, related to an iframe and JavaScript that accesses certain style sheets properties. | ||||
| CVE-2004-2260 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |

| CVE-2006-1834 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings. | ||||
| CVE-2005-3006 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| The mail client in Opera before 8.50 opens attached files from the user's cache directory without warning the user, which might allow remote attackers to inject arbitrary web script and spoof attachment filenames. | ||||

| Buffer overflow in Opera 7.02 Build 2668 allows remote attackers to crash Opera via a long HTTP request ending in a .ZIP extension. | ||||
| CVE-2004-2570 | 1 Opera | 1 Opera Browser | 2026-04-16 | 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-2004-1810 | 1 Opera | 1 Opera Browser | 2026-04-16 | 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. | ||||
