Multiple vulnerabilities have been discovered in Icedove, Debian's version of the Mozilla Thunderbird mail client. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2012-3982 Multiple unspecified vulnerabilities in the browser engine allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. CVE-2012-3986 Icedove does not properly restrict calls to DOMWindowUtils methods, which allows remote attackers to bypass intended access restrictions via crafted JavaScript code. CVE-2012-3990 A Use-after-free vulnerability in the IME State Manager implementation allows remote attackers to execute arbitrary code via unspecified vectors, related to the nsIContent::GetNameSpaceID function. CVE-2012-3991 Icedove does not properly restrict JSAPI access to the GetProperty function, which allows remote attackers to bypass the Same Origin Policy and possibly have unspecified other impact via a crafted web site. CVE-2012-4179 A use-after-free vulnerability in the nsHTMLCSSUtils::CreateCSSPropertyTxn function allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors. CVE-2012-4180 A heap-based buffer overflow in the nsHTMLEditor::IsPrevCharInNodeWhitespace function allows remote attackers to execute arbitrary code via unspecified vectors. CVE-2012-4182 A use-after-free vulnerability in the nsTextEditRules::WillInsert function allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors. CVE-2012-4186 A heap-based buffer overflow in the nsWav-eReader::DecodeAudioData function allows remote attackers to execute arbitrary code via unspecified vectors. CVE-2012-4188 A heap-based buffer overflow in the Convolve3x3 function allows remote attackers to execute arbitrary code via unspecified vectors. For the stable distribution (squeeze), these problems have been fixed in version 3.0.11-1+squeeze14. For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 10.0.9-1. We recommend that you upgrade your icedove packages.
