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-2008-4725 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera 9.52 allows remote attackers to inject arbitrary web script or HTML via the query string, which is not properly escaped before storage in the History Search database (aka md.dat), a different vector than CVE-2008-4696. NOTE: some of these issues were addressed before 9.60.
CVE-2008-4698 1 Opera 1 Opera Browser 2024-11-21 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-2008-4697 1 Opera 1 Opera Browser 2024-11-21 4.3 MEDIUM N/A
The Fast Forward feature in Opera before 9.61, when a page is located in a frame, executes a javascript: URL in the context of the outermost page instead of the page that contains this URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks.
CVE-2008-4694 1 Opera 1 Opera Browser 2024-11-21 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-2008-4292 1 Opera 1 Opera Browser 2024-11-21 10.0 HIGH N/A
Opera before 9.52 does not check the CRL override upon encountering a certificate that lacks a CRL, which has unknown impact and attack vectors. NOTE: it is not clear whether this is a vulnerability, but the vendor included it in a security section of the advisory.
CVE-2008-4200 1 Opera 1 Opera Browser 2024-11-21 6.4 MEDIUM N/A
Opera before 9.52 does not ensure that the address field of a news feed represents the feed's actual URL, which allows remote attackers to change this field to display the URL of a page containing web script controlled by the attacker.
CVE-2008-4199 1 Opera 1 Opera Browser 2024-11-21 5.0 MEDIUM N/A
Opera before 9.52 does not prevent use of links from web pages to feed source files on the local disk, which might allow remote attackers to determine the validity of local filenames via vectors involving "detection of JavaScript events and appropriate manipulation."
CVE-2008-4198 1 Opera 1 Opera Browser 2024-11-21 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.
CVE-2008-4197 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2024-11-21 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-2008-4196 1 Opera 1 Opera Browser 2024-11-21 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-2008-4195 1 Opera 1 Opera Browser 2024-11-21 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.
CVE-2008-3078 1 Opera 1 Opera Browser 2024-11-21 7.8 HIGH N/A
Opera before 9.51 does not properly manage memory within functions supporting the CANVAS element, which allows remote attackers to read uninitialized memory contents by using JavaScript to read a canvas image.
CVE-2008-2716 1 Opera 1 Opera Browser 2024-11-21 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 9.5 allows remote attackers to spoof the contents of trusted frames on the same parent page by modifying the location, which can facilitate phishing attacks.
CVE-2008-2715 1 Opera 1 Opera Browser 2024-11-21 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.
