Updated iceape/sqlite3 packages fix security vulnerabilities

Updated iceape packages fix security issues. The sqlite3 package has been updated as well since the new iceape version requires the SQLITE_ENABLE_DBSTAT_VTAB feature to be enabled in sqlite. This sqlite3 update also enables ICU support, fixing bug #16814 .

Use-after-free vulnerability in the MediaStream playback feature in Mozilla Firefox before 40.0 allows remote attackers to execute arbitrary code via unspecified use of the Web Audio API. (CVE-2015-4477)

Mozilla Firefox before 40.0 allows man-in-the-middle attackers to bypass a mixed-content protection mechanism via a feed: URL in a POST request. (CVE-2015-4483)

The nsCSPHostSrc::permits function in dom/security/nsCSPUtils.cpp in Mozilla Firefox before 40.0 does not implement the Content Security Policy Level 2 exceptions for the blob, data, and filesystem URL schemes during wildcard source-expression matching, which might make it easier for remote attackers to conduct cross-site scripting (XSS) attacks by leveraging unexpected policy-enforcement behavior. (CVE-2015-4490)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. (CVE-2015-4500)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. (CVE-2015-4501)

The lut_inverse_interp16 function in the QCMS library in Mozilla Firefox before 41.0 allows remote attackers to obtain sensitive information or cause a denial of service (buffer over-read and application crash) via crafted attributes in the ICC 4 profile of an image. (CVE-2015-4504)

The SavedStacks class in the JavaScript implementation in Mozilla Firefox before 41.0, when the Debugger API is enabled, allows remote attackers to cause a denial of service (getSlotRef assertion failure and application exit) or possibly execute arbitrary code via a crafted web site. (CVE-2015-4507)

Mozilla Firefox before 41.0, when reader mode is enabled, allows remote attackers to spoof the relationship between address-bar URLs and web content via a crafted web site. (CVE-2015-4508)

Race condition in the WorkerPrivate::NotifyFeatures function in Mozilla Firefox before 41.0 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) by leveraging improper interaction between shared workers and the IndexedDB implementation. (CVE-2015-4510)

Heap-based buffer overflow in the nestegg_track_codec_data function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via a crafted header in a WebM video. (CVE-2015-4511)

Use-after-free vulnerability in the HTMLVideoElement interface in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via crafted JavaScript code that modifies the URI table of a media element, aka ZDI-CAN-3176. (CVE-2015-4509)

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering. (CVE-2015-4512)

js/src/proxy/Proxy.cpp in Mozilla Firefox before 41.0 mishandles certain receiver arguments, which allows remote attackers to bypass intended window access restrictions via a crafted web site. (CVE-2015-4502)

Mozilla Firefox before 41.0 allows remote attackers to bypass certain ECMAScript 5 (aka ES5) API protection mechanisms and modify immutable properties, and consequently…
