Description:
A vulnerability has been reported in Opera Web Browser, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when processing overly long URLs. This can be exploited to cause a heap-based buffer overflow by passing an overly long URL (more than 256 bytes) in a tag.
Successful exploitation allows execution of arbitrary code when a user visits a malicious website.
The vulnerability is reported in versions 9.0 and 9.01 on Windows and Linux. Version 8.x is reportedly not affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
