Gentoo Linux Security Advisory

Title: Opera: Multiple vulnerabilities (GLSA 200903-30)
Severity: normal
Exploitable: remote
Date: March 16, 2009
Updated: March 17, 2009
Bug(s): #247229, #261032
ID: 200903-30

Synopsis

Multiple vulnerabilities were found in Opera, the worst of which allow for the execution of arbitrary code.

Background

Opera is a fast web browser that is available free of charge.

Affected Packages

Package: www-client/opera
Vulnerable: < 9.64
Unaffected: >= 9.64
Architectures: All supported architectures


Description

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).


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.

Resolution

All Opera users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.64"
