Beschreibung: | Summary: The remote host is missing an update to iceweasel announced via advisory DSA 2565-1.
Vulnerability Insight: 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.
Solution: We recommend that you upgrade your iceweasel packages.
