Where

From remote

Impact
DoS (Denial of Service)

This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system.


System access

This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.


Exposure of sensitive information

Vulnerabilities where documents or credentials are leaked or can be revealed either locally or from remote.


Security Bypass

This covers vulnerabilities or security issues where malicious users or people can bypass certain security mechanisms of the application.

The actual impact varies significantly depending on the design and purpose of the affected application.


Spoofing

This covers various vulnerabilities where it is possible for malicious users or people to impersonate other users or systems.


Description

Some vulnerabilities have been reported in Opera, which can be exploited by malicious people to conduct spoofing and cross-site scripting attacks, bypass certain security restrictions, disclose potentially sensitive information, or potentially compromise a user's system.

1) An unspecified error exists when Opera is executed as a protocol handler. This can be exploited to cause a crash and potentially execute arbitrary code.

NOTE: Reportedly, the vulnerability only affects Opera for Windows.

2) The problem is that a web page can change the address of frames from other sites opened inside a pop-up window. This can be exploited to load malicious content into a frame of a trusted website.

3) An unspecified error can be exploited to conduct cross-site scripting attacks. No further information is currently available.

4) An error exists in the processing of custom shortcut and menu commands. This can be exploited to execute applications with potentially dangerous parameters, created from uninitialized memory.

Successful exploitation may allow execution of arbitrary code, but requires that a user is tricked into modifying shortcuts or menu files.

5) An error exists while reporting websites as secure for browsing. This can be exploited to determine the reporting of an insecure website as secure by including a frame with content from a secure website.

6) An error exists when checking if a web page links to a local file. This can be exploited to link to local feed source files and potentially determine if a file is present on the local system.

7) An error exists when processing news feed subscription requests. This can be exploited to change the address field to the address of the malicious web page and mislead a user.

The vulnerabilities are reported in versions prior to 9.52.

Solution

Update to version 9.52.
