Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200903-30
(Opera: Multiple vulnerabilities)

Multiple vulnerabilities were discovered in Opera:
Vitaly McLain reported a heap-based buffer overflow when processing
host names in file:// URLs (CVE-2008-5178).

when processing web pages that trigger an invalid pointer calculation
and heap corruption (CVE-2008-5679).

An unspecified vulnerability reveals random data
Tavis Ormandy of the Google Security Team reported a vulnerability
when processing JPEG images that may corrupt memory

Impact :

A remote attacker could entice a user to open a specially crafted JPEG
image to cause a Denial of Service or execute arbitrary code, to
process an overly long file:// URL or to open a specially crafted web
page to execute arbitrary code. He could also read existing
subscriptions and force subscriptions to arbitrary feed URLs, as well
as inject arbitrary web script or HTML via built-in XSLT templates.

Workaround :

There is no known workaround at this time.
