CVE-2009-2577 1 Opera 1 Opera Browser 2024-11-21 5.0 MEDIUM N/A
Opera 9.52 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption, and application hang) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479.
CVE-2009-2540 1 Opera 1 Opera Browser 2024-11-21 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-2009-2351 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
Opera 9.52 and earlier does not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header, a related issue to CVE-2009-1312. NOTE: it was later reported that 10.00 Beta 3 Build 1699 is also affected.
CVE-2009-2070 1 Opera 1 Opera Browser 2024-11-21 6.8 MEDIUM N/A
Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
CVE-2009-2068 1 Opera 1 Opera 2024-11-21 5.8 MEDIUM N/A
Google Chrome detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
CVE-2009-2067 1 Opera 1 Opera Browser 2024-11-21 6.8 MEDIUM N/A
Opera detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages."
CVE-2009-2063 1 Opera 1 Opera Browser 2024-11-21 6.8 MEDIUM N/A
Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.
CVE-2009-2059 1 Opera 1 Opera Browser 2024-11-21 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-2009-1599 2 Adobe, Opera 2 Acrobat Reader, Opera Browser 2024-11-21 9.3 HIGH N/A
Opera executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI. NOTE: the researcher reports that Adobe's position is "a PDF file is active content."
CVE-2009-1234 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
Opera 9.64 allows remote attackers to cause a denial of service (application crash) via an XML document containing a long series of start-tags with no corresponding end-tags. NOTE: it was later reported that 9.52 is also affected.
CVE-2009-0916 1 Opera 1 Opera Browser 2024-11-21 10.0 HIGH N/A
Unspecified vulnerability in Opera before 9.64 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2009-0915 1 Opera 1 Opera Browser 2024-11-21 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.
CVE-2009-0914 1 Opera 1 Opera Browser 2024-11-21 9.3 HIGH N/A
Opera before 9.64 allows remote attackers to execute arbitrary code via a crafted JPEG image that triggers memory corruption.
CVE-2008-7297 1 Opera 1 Opera Browser 2024-11-21 5.8 MEDIUM N/A
Opera cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.
CVE-2008-7245 1 Opera 1 Opera Browser 2024-11-21 5.0 MEDIUM N/A
Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.
CVE-2008-5683 1 Opera 1 Opera Browser 2024-11-21 7.8 HIGH N/A
Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.
CVE-2008-5682 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 9.63 allows remote attackers to inject arbitrary web script or HTML via built-in XSLT templates.
CVE-2008-5681 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
Opera before 9.63 does not block unspecified "scripted URLs" during the feed preview, which allows remote attackers to read existing subscriptions and force subscriptions to arbitrary feed URLs.
CVE-2008-5680 1 Opera 1 Opera Browser 2024-11-21 9.3 HIGH N/A
Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178.
CVE-2008-5679 1 Opera 1 Opera 2024-11-21 9.3 HIGH N/A
The HTML parsing engine in Opera before 9.63 allows remote attackers to execute arbitrary code via crafted web pages that trigger an invalid pointer calculation and heap corruption.
