Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-4201 CVE-2012-4207 CVE-2012-4216 CVE-2012-5829
CVE-2012-5842
Debian Bug :
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.
For the stable distribution (squeeze), these problems have been fixed in
version 3.5.16-20.
For the testing distribution (wheezy), these problems have been fixed in
version 10.0.11esr-1.
For the unstable distribution (sid), these problems have been fixed in
version 10.0.11esr-1.
We recommend that you upgrade your iceweasel packages.
