More information:

Multiple vulnerabilities have been discovered in Iceweasel, Debian's version of the Mozilla Firefox web browser. 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:

    Iceweasel 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:

    Iceweasel 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 3.5.16-19.

For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 10.0.8esr-1.

We recommend that you upgrade your iceweasel packages.
