Description:
Some vulnerabilities have been reported in Opera, which can be exploited by malicious people to bypass certain security restrictions, disclose sensitive information, and compromise a user's system.
1) An unspecified error can be exploited via certain plugins to conduct cross-domain scripting attacks.
2) A boundary error exists in the processing of "Subject Alternative Name" TLS extensions. This can be exploited to cause a heap-based buffer overflow via an overly long "Subject Alternative Name" included in a malicious TLS certificate.
3) An unspecified error within Rich text editing when using designMode can be exploited to conduct cross-domain scripting attacks.
4) An error within the processing of color palettes within bitmaps can be exploited to disclose the contents of random memory areas.
The vulnerabilities are reported in versions prior to 9.25.
Solution:
Update to version 9.25.
