Описание

Multiple vulnerabilities were discovered in Opera:

Vitaly McLain reported a heap-based buffer overflow when processing host names in file:// URLs (CVE-2008-5178).
Alexios Fakos reported a vulnerability in the HTML parsing engine when processing web pages that trigger an invalid pointer calculation and heap corruption (CVE-2008-5679).
Red XIII reported that certain text-area contents can be manipulated to cause a buffer overlow (CVE-2008-5680).
David Bloom discovered that unspecified "scripted URLs" are not blocked during the feed preview (CVE-2008-5681).
Robert Swiecki of the Google Security Team reported a Cross-site scripting vulnerability (CVE-2008-5682).
An unspecified vulnerability reveals random data (CVE-2008-5683).
Tavis Ormandy of the Google Security Team reported a vulnerability when processing JPEG images that may corrupt memory (CVE-2009-0914).

Воздействие

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.

Обход

There is no known workaround at this time.

Решение

All Opera users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/opera-9.64"
