HTTP: Opera File URL Overflow

This signature detects attempts to exploit a known vulnerability in Opera Software (version 9.62 and prior). An attacker can create a malicious Web site containing dangerous URL links, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.

Extended Description

Opera Web Browser is prone to a heap-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input before copying it to an insufficiently sized buffer. Attackers can exploit this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions. Opera Web Browser 9.62 is vulnerable; other versions may also be affected.
