Package : tiff
Vulnerability : buffer overflow
Problem type : local
Debian-specific: no
CVE ID : CVE-2012-5581
Debian Bug : 694693

The tiff library for handling TIFF image files contained a stack-based
buffer overflow, potentially allowing attackers who can submit such
files to a vulnerable system to execute arbitrary code.

For the stable distribution (squeeze), this problem has been fixed in
version 3.9.4-5+squeeze8.

For the testing distribution (wheezy) and the unstable distribution
(sid), this problem has been fixed in version 4.0.2-1 of the tiff
package, and version 3.9.6-10 of the tiff3 package.

We recommend that you upgrade your tiff packages.

Package : icedove
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-4201 CVE-2012-4207 CVE-2012-4216 CVE-2012-5829
CVE-2012-5842

Multiple vulnerabilities have been found in Icedove, Debian's version
of the Mozilla Thunderbird mail and news client.

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-2012-4207
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-2012-4216
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.

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.

For the stable distribution (squeeze), these problems have been fixed in
version 3.0.11-1+squeeze15.

For the unstable distribution (sid), these problems have been fixed in
version 10.0.11-1.

We recommend that you upgrade your icedove packages.
