Advisory: External news readers and e-mail clients can be used to execute arbitrary code
External news readers and e-mail clients can be used to execute arbitrary code.
Severity: Highly Severe
All versions of Opera for Desktop prior to Opera 9.24.
If a user has configured Opera to use an external newsgroup client or e-mail application, specially crafted Web pages can cause Opera to run that application incorrectly. In some cases this can lead to execution of arbitrary code.
Opera Software has released Opera 9.24, where this issue has been fixed.
Thanks to Michael A. Puls II for reporting this issue to Opera Software.
