Debian DSA-2583-1 : iceweasel - several vulnerabilities

critical Nessus Plugin ID 63193

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple vulnerabilities have been found in Iceweasel, the Debian web browser based on Mozilla Firefox :

- CVE-2012-5829 Heap-based buffer overflow in the nsWindow::OnExposeEvent function could allow remote attackers to execute arbitrary code.

- CVE-2012-5842 Multiple unspecified vulnerabilities in the browser engine could allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code.

- CVE-2012-4207 The HZ-GB-2312 character-set implementation does not properly handle a ~ (tilde) character in proximity to a chunk delimiter, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.

- CVE-2012-4201 The evalInSandbox implementation uses an incorrect context during the handling of JavaScript code that sets the location.href property, which allows remote attackers to conduct cross-site scripting (XSS) attacks or read arbitrary files by leveraging a sandboxed add-on.

- CVE-2012-4216 Use-after-free vulnerability in the gfxFont::GetFontEntry function allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.

Solution

Upgrade the iceweasel packages.

For the stable distribution (squeeze), these problems have been fixed in version 3.5.16-20.
