CVE-2008-3079 2 Microsoft, Opera 2 Windows, Opera 2025-04-09 10.0 HIGH N/A
Unspecified vulnerability in Opera before 9.51 on Windows allows attackers to execute arbitrary code via unknown vectors.
CVE-2008-4196 1 Opera 1 Opera Browser 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 9.52 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2009-3048 4 Conectiva, Freebsd, Opera and 1 more 4 Linux, Freebsd, Opera Browser and 1 more 2025-04-09 4.3 MEDIUM N/A
Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file."
CVE-2009-2068 1 Opera 1 Opera 2025-04-09 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-2008-4694 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Unspecified vulnerability in Opera before 9.60 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a redirect that specifies a crafted URL.
CVE-2008-5679 1 Opera 1 Opera 2025-04-09 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.
CVE-2008-3172 1 Opera 1 Opera 2025-04-09 6.8 MEDIUM N/A
Opera allows web sites to set cookies for country-specific top-level domains that have DNS A records, such as co.tv, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session, aka "Cross-Site Cooking."
CVE-2008-4794 1 Opera 1 Opera 2025-04-09 9.3 HIGH 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-2009-3046 1 Opera 1 Opera Browser 2025-04-09 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-2008-4698 1 Opera 1 Opera Browser 2025-04-09 5.8 MEDIUM N/A
Opera before 9.61 does not properly block scripts during preview of a news feed, which allows remote attackers to create arbitrary new feed subscriptions and read the contents of arbitrary feeds.
CVE-2008-1764 1 Opera 1 Opera 2025-04-09 9.3 HIGH N/A
Unspecified vulnerability in Opera before 9.27 has unknown impact and attack vectors related to "keyboard handling of password inputs."
CVE-2009-2351 1 Opera 1 Opera Browser 2025-04-09 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-2007-1563 1 Opera 1 Opera Browser 2025-04-09 6.8 MEDIUM 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-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-2008-2715 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 9.5 allows remote attackers to read cross-domain images via HTML CANVAS elements that use the images as patterns.
CVE-2007-2274 1 Opera 1 Opera Browser 2025-04-09 7.8 HIGH N/A
The BitTorrent implementation in Opera 9.2 allows remote attackers to cause a denial of service (CPU consumption and application crash) via a malformed torrent file. NOTE: the original disclosure refers to this as a memory leak, but it is not certain.
CVE-2008-4695 1 Opera 1 Opera 2025-04-09 9.3 HIGH N/A
Opera before 9.60 allows remote attackers to obtain sensitive information and have unspecified other impact by predicting the cache pathname of a cached Java applet and then launching this applet from the cache, leading to applet execution within the local-machine context.
CVE-2007-4944 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
The canvas.createPattern function in Opera 9.x before 9.22 for Linux, FreeBSD, and Solaris does not clear memory before using it to process a new pattern, which allows remote attackers to obtain sensitive information (memory contents) via JavaScript.
CVE-2009-1234 1 Opera 1 Opera Browser 2025-04-09 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-2008-4195 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
Opera before 9.52 does not properly restrict the ability of a framed web page to change the address associated with a different frame, which allows remote attackers to trigger the display of an arbitrary address in a frame via unspecified use of web script.
