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.

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.
