CVE-2012-6472 2 Opera, Unix 2 Opera Browser, Unix 2025-04-11 4.6 MEDIUM N/A
Opera before 12.12 on UNIX uses weak permissions for the profile directory, which allows local users to obtain sensitive information by reading a (1) cache file, (2) password file, or (3) configuration file, or (4) possibly gain privileges by modifying or overwriting a configuration file.
CVE-2012-6467 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 12.10 follows Internet shortcuts that are referenced by a (1) IMG element or (2) other inline element, which makes it easier for remote attackers to conduct phishing attacks via a crafted web site, as exploited in the wild in November 2012.
CVE-2011-1337 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages.
CVE-2010-2421 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH N/A
Multiple unspecified vulnerabilities in Opera before 10.54 have unknown impact and attack vectors related to (1) "extremely severe," (2) "highly severe," (3) "moderately severe," and (4) "less severe" issues.
CVE-2011-2619 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a gradient with many stops, related to the implementation of CANVAS elements, SVG, and Cascading Style Sheets (CSS).
CVE-2010-4050 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 10.63 allows remote attackers to cause a denial of service (memory corruption) by referencing an SVG document in an IMG element.
CVE-2011-2612 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by progorod.ru.
CVE-2013-3210 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 12.15 does not properly block top-level domains in Set-Cookie headers, which allows remote attackers to obtain sensitive information by leveraging control of a different web site in the same top-level domain.
CVE-2010-4584 1 Opera 1 Opera Browser 2025-04-11 2.6 LOW N/A
Opera before 11.00, when Opera Turbo is used, does not properly present information about problematic X.509 certificates on https web sites, which might make it easier for remote attackers to spoof trusted content via a crafted web site.
CVE-2011-4684 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH N/A
Opera before 11.60 does not properly handle certificate revocation, which has unspecified impact and remote attack vectors related to "corner cases."
CVE-2011-2617 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to selecting a text node, and closed pop-up windows, removed pop-up windows, and IFRAME elements.
CVE-2011-2614 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn.
CVE-2013-1638 1 Opera 1 Opera Browser 2025-04-11 9.3 HIGH N/A
Opera before 12.13 allows remote attackers to execute arbitrary code via crafted clipPaths in an SVG document.
CVE-2012-3560 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.
CVE-2009-2059 1 Opera 1 Opera Browser 2025-04-09 6.8 MEDIUM N/A
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.
CVE-2007-1115 1 Opera 1 Opera Browser 2025-04-09 4.3 MEDIUM N/A
The child frames in Opera 9 before 9.20 inherit the default charset from the parent window when a charset is not specified in an HTTP Content-Type header or META tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated using the UTF-7 character set.
CVE-2007-0127 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
CVE-2007-0126 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Heap-based buffer overflow in Opera 9.02 allows remote attackers to execute arbitrary code via a JPEG file with an invalid number of index bytes in the Define Huffman Table (DHT) marker.
CVE-2009-3045 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
Opera before 10.00 trusts root X.509 certificates signed with the MD2 algorithm, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted server certificate.
CVE-2008-4198 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
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.
