CVE-2006-1834 1 Opera 1 Opera Browser 2018-10-18 5.1 MEDIUM N/A
Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings.
CVE-2007-1737 1 Opera 1 Opera Browser 2018-10-16 7.5 HIGH N/A
Opera 9.10 does not check URLs embedded in (1) object or (2) iframe HTML tags against the phishing site blacklist, which allows remote attackers to bypass phishing protection.
CVE-2007-1115 1 Opera 1 Opera Browser 2018-10-16 4.3 MEDIUM 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.
CVE-2006-6970 1 Opera 1 Opera Browser 2018-10-16 5.0 MEDIUM N/A
Opera 9.10 Final allows remote attackers to bypass the Fraud Protection mechanism by adding certain characters to the end of a domain name, as demonstrated by the "." and "/" characters, which is not caught by the blacklist filter.
CVE-2007-6523 1 Opera 1 Opera Browser 2018-10-15 7.8 HIGH N/A
Algorithmic complexity vulnerability in Opera 9.50 beta and 9.x before 9.25 allows remote attackers to cause a denial of service (CPU consumption) via a crafted bitmap (BMP) file that triggers a large number of calculations and checks.
CVE-2007-6524 1 Opera 1 Opera Browser 2018-10-15 7.8 HIGH N/A
Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420.
CVE-2007-3819 1 Opera 1 Opera Browser 2018-10-15 5.0 MEDIUM N/A
Opera 9.21 allows remote attackers to spoof the data: URI scheme in the address bar via a long URI with trailing whitespace, which prevents the beginning of the URI from being displayed.
CVE-2008-7245 1 Opera 1 Opera Browser 2018-10-11 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-2008-5680 1 Opera 1 Opera Browser 2018-10-11 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 2018-10-11 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-2008-5428 2 Microsoft, Opera 2 Windows Xp, Opera 2018-10-11 4.3 MEDIUM 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-2008-4725 1 Opera 1 Opera Browser 2018-10-11 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-2008-4696 1 Opera 1 Opera 2018-10-11 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera before 9.61 allows remote attackers to inject arbitrary web script or HTML via the anchor identifier (aka the "optional fragment"), which is not properly escaped before storage in the History Search database (aka md.dat).
CVE-2010-2576 1 Opera 1 Opera Browser 2018-10-10 6.8 MEDIUM N/A
Opera before 10.61 does not properly suppress clicks on download dialogs that became visible after a recent tab change, which allows remote attackers to conduct clickjacking attacks, and consequently execute arbitrary code, via vectors involving (1) closing a tab or (2) hiding a tab, a related issue to CVE-2005-2407.
CVE-2010-2121 1 Opera 1 Opera Browser 2018-10-10 4.3 MEDIUM N/A
Opera 9.52 allows remote attackers to cause a denial of service (resource consumption) via JavaScript code containing an infinite loop that creates IFRAME elements for invalid (1) news:// or (2) nntp:// URIs.
CVE-2010-1993 1 Opera 1 Opera Browser 2018-10-10 5.0 MEDIUM N/A
Opera 9.52 does not properly handle an IFRAME element with a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (resource consumption) via an HTML document with many IFRAME elements.
CVE-2010-1989 1 Opera 1 Opera Browser 2018-10-10 5.0 MEDIUM N/A
Opera 9.52 executes a mail application in situations where an IMG element has a SRC attribute that is a redirect to a mailto: URL, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many images, a related issue to CVE-2010-0181.
CVE-2009-3269 1 Opera 1 Opera Browser 2018-10-10 5.0 MEDIUM N/A
Opera 9.52 and earlier allows remote attackers to cause a denial of service (CPU consumption) via a series of automatic submissions of a form containing a KEYGEN element, a related issue to CVE-2009-1828.
CVE-2009-3265 1 Opera 1 Opera Browser 2018-10-10 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera 9 and 10 allows remote attackers to inject arbitrary web script or HTML via a (1) RSS or (2) Atom feed, related to the rendering of the application/rss+xml content type as "scripted content." NOTE: the vendor reportedly considers this behavior a "design feature," not a vulnerability.
CVE-2009-2577 1 Opera 1 Opera Browser 2018-10-10 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.
