Opera < 9.63 Multiple Vulnerabilities

high Nessus Plugin ID 35185

Synopsis

The remote host contains a web browser that is affected by several issues.

Description

The version of Opera installed on the remote host is earlier than 9.63 and thus reportedly affected by several issues :

- It may be possible to execute arbitrary code on the remote system by manipulating certain text-area contents. (920)

- It may be possible to crash the remote browser using certain HTML constructs or inject code under certain conditions. (921)

- It may be possible to trigger a buffer overflow, and potentially execute arbitrary code, by tricking an user to click on a URL that contains exceptionally long host names. (922)

- While previewing news feeds, Opera does not correctly block certain scripted URLs. Such scripts, if not blocked, may be able to subscribe a user to other arbitrary feeds and view contents of the feeds to which the user is currently subscribed. (923)

- By displaying content using XSLT as escaped strings, it may be possible for a website to inject scripted markup. (924)

- SSL server certificates are not properly validated due to an unspecified error. (CVE-2012-1251)

Solution

Upgrade to Opera 9.63 or later.
