Updated nss, firefox and thunderbird packages fix security vulnerabilities

In the NSS library before version 3.16, in a wildcard certificate, the wildcard character was embedded within the U-label of an internationalized domain name, which is not in accordance with RFC 6125 (CVE-2014-1492).

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox or Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running it (CVE-2014-1493, CVE-2014-1510, CVE-2014-1511, CVE-2014-1512, CVE-2014-1513, CVE-2014-1514).

Several information disclosure flaws were found in the way Firefox and Thunderbird processed malformed web content. An attacker could use these flaws to gain access to sensitive information such as cross-domain content or protected memory addresses or, potentially, cause Firefox or Thunderbird to crash (CVE-2014-1497, CVE-2014-1508, CVE-2014-1505).

A memory corruption flaw was found in the way Firefox and Thunderbird rendered certain PDF files. An attacker able to trick a user into installing a malicious extension could use this flaw to crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox or Thunderbird (CVE-2014-1509).

Updated iceape packages fix multiple vulnerabilities

Updated iceape packages fix security issues:

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. (CVE-2014-1493)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. (CVE-2014-1494)

Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 might allow local users to gain privileges by modifying the extracted Mar contents during an update. (CVE-2014-1496)

mozilla::WaveReader::DecodeAudioData function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process heap memory, cause a denial of service (out-of-bounds read and application crash), or possibly have unspecified other impact via a crafted WAV file. (CVE-2014-1497)

The crypto.generateCRMFRequest method in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not properly validate a certain key type, which allows remote attackers to cause a denial of service (application crash) via vectors that trigger generation of a key that supports the Elliptic Curve ec-dual-use algorithm. (CVE-2014-1498)

Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to spoof the domain name in the WebRTC (1) camera or (2) microphone permission prompt by triggering navigation at a certain time during generation of this prompt. (CVE-2014-1499)

Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (resource consumption and application hang) via onbeforeunload events that trigger background JavaScript execution. (CVE-2014-1500)

The (1) WebGL.compressedTexImage2D and (2) WebGL.compressedTexSubImage2D functions in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to bypass the Same Origin Policy and render content in a different domain via unspecified vectors. (CVE-2014-1502)

The session-restore feature in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not consider the Content Security Policy of a data: URL, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document that is accessed after a browser restart. (CVE-2014-1504)

The libxul.so!gfxContext::Polygon function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process memory, cause a denial of service (out-of-bounds read and application crash), or possibly bypass the Same Origin Policy via vectors involving MathML polygon rendering. (CVE-2014-1508)

Buffer overflow in the _cairo_truetype_index_to_ucs4 function in cairo, as used in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25, allows remote attackers to execute arbitrary code via a crafted extension that renders fonts in a PDF document. (CVE-2014-1509)

SVG filter implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive displacement-correlation information, and possibly bypass the Same Origin Policy and read text from a different domain, via a timing attack involving feDisplacementMap elements, a related issue to CVE-2013-1693. (CVE-2014-1505)

The Web IDL implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4,…
