CVSS v3.1 |
| 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." |
| 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. |
| 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. |
| Integer overflow in Opera 8.54 and earlier allows remote attackers to execute arbitrary code via a JPEG image with large height and width values, which causes less memory to be allocated than intended. |
| Integer overflow in GameMaker IDE below 2024.14.0 version can lead to can lead to application crashes through denial-of-service attacks (DoS). GameMaker users who use the network_create_server() function in their projects are urged to update and recompile immediately. |
| Characters from languages are such as Arabic, Hebrew are displayed from RTL (Right To Left) order in Opera 37.0.2192.105088 for Android, due to mishandling of several unicode characters such as U+FE70, U+0622, U+0623 etc and how they are rendered combined with (first strong character) such as an IP address or alphabet could lead to a spoofed URL. It was noticed that by placing neutral characters such as "/", "?" in filepath causes the URL to be flipped and displayed from Right To Left. However, in order for the URL to be spoofed the URL must begin with an IP address followed by neutral characters as omnibox considers IP address to be combination of punctuation and numbers and since LTR (Left To Right) direction is not properly enforced, this causes the entire URL to be treated and rendered from RTL (Right To Left). However, it doesn't have be an IP address, what matters is that first strong character (generally, alphabetic character) in the URL must be an RTL character. |
| Opera Mini 13 and Opera Stable 36 allow remote attackers to spoof the displayed URL via a crafted HTML document, related to the about:blank URL. |
| The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site. |
| The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue. |
| The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack. |
| The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack. |
| Unspecified vulnerability in Opera Mail before 2016-02-16 on Windows allows user-assisted remote attackers to execute arbitrary code via a crafted e-mail message. |
| The downloads manager in Opera before 11.01 on Windows does not properly determine the pathname of the filesystem-viewing application, which allows user-assisted remote attackers to execute arbitrary code via a crafted web site that hosts an executable file. |
| Integer truncation error in opera.dll in Opera before 11.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via an HTML form with a select element that contains a large number of children. |
| The Cascading Style Sheets (CSS) Extensions for XML implementation in Opera before 11.01 recognizes links to javascript: URLs in the -o-link property, which makes it easier for remote attackers to bypass CSS filtering via a crafted URL. |
| The Delete Private Data feature in Opera before 11.01 does not properly implement the "Clear all email account passwords" option, which might allow physically proximate attackers to access an e-mail account via an unattended workstation. |
| Unspecified vulnerability in Opera before 11.01 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by vkontakte.ru. |
| Opera before 11.01 does not properly implement Wireless Application Protocol (WAP) dropdown lists, which allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted WAP document. |
| Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages. |
| Opera before 11.50 does not properly restrict data: URIs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site. |
