Debian: Security update for Icedove
Multiple vulnerabilities have been found in Icedove, Debian’s version of the Mozilla Thunderbird mail and news client. 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. 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.
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. Heap-based buffer overflow in the nsWindow::OnExposeEvent function could allow remote attackers to execute arbitrary code. 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.
Updated packages are available from security.debian.org.

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.
