Description

The remote host is running the Opera web browser.

Versions of Opera earlier than 12.01 are potentially affected by multiple vulnerabilities :

- An error exists in the handling of certain URLs that can lead to memory corruption and possible code execution. (1016)

- Errors exist in the handling of DOM elements and certain HTML characters that can lead to cross-site scripting. (1025, 1026)

- Download dialog boxes can be made small enough that users may not realize they are accepting a download and further, executing such a download. (1027)

- An attacker could cause an application crash by tricking a user into connecting to a malicious site, as demonstrated by the Lenovo 'Shop Now' page. (CVE-2012-4146)
