CVE-2009-2059 1 Opera 1 Opera Browser 2025-04-09 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-2009-2063 1 Opera 1 Opera Browser 2025-04-09 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-2008-5428 2 Microsoft, Opera 2 Windows Xp, Opera 2025-04-09 N/A
Opera 9.51 on Windows XP does not properly handle (1) multipart/mixed e-mail messages with many MIME parts and possibly (2) e-mail messages with many "Content-type: message/rfc822;" headers, which allows remote attackers to cause a denial of service (stack consumption or other resource consumption) via a large e-mail message, a related issue to CVE-2006-1173.
CVE-2008-1081 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.26 allows user-assisted remote attackers to execute arbitrary script via images that contain custom comments, which are treated as script when the user displays the image properties.
CVE-2008-1082 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 9.26 allows remote attackers to "bypass sanitization filters" and conduct cross-site scripting (XSS) attacks via crafted attribute values in an XML document, which are not properly handled during DOM presentation.
CVE-2009-2068 1 Opera 1 Opera 2025-04-09 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-2009-2351 1 Opera 1 Opera Browser 2025-04-09 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-2006-6955 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.
CVE-2007-1563 1 Opera 1 Opera Browser 2025-04-09 N/A
The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.
CVE-2008-4197 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2025-04-09 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-2009-4071 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 10.10, when exception stacktraces are enabled, places scripting error messages from a web site into variables that can be read by a different web site, which allows remote attackers to obtain sensitive information or conduct cross-site scripting (XSS) attacks via unspecified vectors.
CVE-2009-3013 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.
CVE-2007-0126 1 Opera 1 Opera Browser 2025-04-09 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-2007-3929 1 Opera 1 Opera Browser 2025-04-09 N/A
Use-after-free vulnerability in the BitTorrent support in Opera before 9.22 allows user-assisted remote attackers to execute arbitrary code via a crafted header in a torrent file, which leaves a dangling pointer to an invalid object.
CVE-2009-3832 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-09 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-2006-4819 1 Opera 1 Opera Browser 2025-04-09 N/A
Heap-based buffer overflow in Opera 9.0 and 9.01 allows remote attackers to execute arbitrary code via a long URL in a tag (long link address).
CVE-2009-1599 2 Adobe, Opera 2 Acrobat Reader, Opera Browser 2025-04-09 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-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-09 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-2008-4794 1 Opera 1 Opera 2025-04-09 N/A
Opera before 9.62 allows remote attackers to execute arbitrary commands via the History Search results page, a different vulnerability than CVE-2008-4696.
CVE-2007-1115 1 Opera 1 Opera Browser 2025-04-09 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.
