CVE-2008-4197 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2024-02-15 9.3 HIGH 8.8 HIGH
Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut.
CVE-2009-3046 1 Opera 1 Opera Browser 2024-02-09 5.0 MEDIUM 7.5 HIGH
Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate.
CVE-2009-2540 1 Opera 1 Opera Browser 2024-02-02 4.3 MEDIUM N/A
Opera, possibly 9.64 and earlier, allows remote attackers to cause a denial of service (memory consumption) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.
CVE-2019-18624 1 Opera 1 Mini 2023-11-07 7.5 HIGH 9.8 CRITICAL
Opera Mini for Android allows attackers to bypass intended restrictions on .apk file download/installation via an RTLO (aka Right to Left Override) approach, as demonstrated by misinterpretation of malicious%E2%80%AEtxt.apk as maliciouskpa.txt. This affects 44.1.2254.142553, 44.1.2254.142659, and 44.1.2254.143214.
CVE-2013-1489 5 Google, Microsoft, Mozilla and 2 more 6 Chrome, Internet Explorer, Firefox and 3 more 2023-11-07 10.0 HIGH N/A
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 10 and Update 11, when running on Windows using Internet Explorer, Firefox, Opera, and Google Chrome, allows remote attackers to bypass the "Very High" security level of the Java Control Panel and execute unsigned Java code without prompting the user via unknown vectors, aka "Issue 53" and the "Java Security Slider" vulnerability.
CVE-2011-0682 1 Opera 1 Opera Browser 2023-11-07 9.3 HIGH N/A
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.
CVE-2015-4000 12 Apple, Canonical, Debian and 9 more 25 Iphone Os, Mac Os X, Safari and 22 more 2023-02-09 4.3 MEDIUM 3.7 LOW
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVE-2015-8960 7 Apple, Google, Ietf and 4 more 18 Safari, Chrome, Transport Layer Security and 15 more 2023-01-30 6.8 MEDIUM 8.1 HIGH
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.
CVE-2018-16135 1 Opera 1 Opera Mini 2023-01-05 N/A 6.5 MEDIUM
The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site.
CVE-2011-3389 9 Canonical, Debian, Google and 6 more 17 Ubuntu Linux, Debian Linux, Chrome and 14 more 2022-11-29 4.3 MEDIUM N/A
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
CVE-2016-4075 1 Opera 2 Opera Browser, Opera Mini 2022-04-06 5.8 MEDIUM 6.1 MEDIUM
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.
CVE-2003-1397 1 Opera 1 Opera Browser 2022-03-01 4.3 MEDIUM N/A
The PluginContext object of Opera 6.05 and 7.0 allows remote attackers to cause a denial of service (crash) via an HTTP request containing a long string that gets passed to the ShowDocument method.
CVE-2003-1396 1 Opera 1 Opera Browser 2022-03-01 6.8 MEDIUM N/A
Heap-based buffer overflow in Opera 6.05 through 7.10 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a filename with a long extension.
CVE-2003-1388 1 Opera 1 Opera Browser 2022-03-01 9.3 HIGH N/A
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-2003-1387 1 Opera 1 Opera Browser 2022-03-01 7.5 HIGH N/A
Buffer overflow in Opera 6.05 and 6.06, and possibly other versions, allows remote attackers to execute arbitrary code via a URL with a long username.
CVE-2003-0870 1 Opera 1 Opera Browser 2022-03-01 7.5 HIGH N/A
Heap-based buffer overflow in Opera 7.11 and 7.20 allows remote attackers to execute arbitrary code via an HREF with a large number of escaped characters in the server name.
CVE-2003-0593 1 Opera 1 Opera Browser 2022-03-01 7.5 HIGH N/A
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.
CVE-2009-3832 2 Microsoft, Opera 2 Windows, Opera Browser 2022-03-01 5.8 MEDIUM N/A
Opera before 10.01 on Windows does not prevent use of Web fonts in rendering the product's own user interface, which allows remote attackers to spoof the address field via a crafted web site.
CVE-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2022-03-01 9.3 HIGH N/A
Opera before 10.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted domain name.
CVE-2009-0915 1 Opera 1 Opera Browser 2022-03-01 6.8 MEDIUM N/A
Opera before 9.64 allows remote attackers to conduct cross-domain scripting attacks via unspecified vectors related to plug-ins.
