Updated iceape packages fix security vulnerabilities
Updated iceape packages fix security issues:
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. (CVE-2015-0814, CVE-2015-0815)
Use-after-free vulnerability in the AppendElements function in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 on Linux, when the Fluendo MP3 plugin for GStreamer is used, allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via a crafted MP3 file. (CVE-2015-0813)
Mozilla Firefox before 37.0 does not require an HTTPS session for lightweight theme add-on installations, which allows man-in-the-middle attackers to bypass an intended user-confirmation requirement by deploying a crafted web site and conducting a DNS spoofing attack against a mozilla.org subdomain. (CVE-2015-0812)
Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 do not properly restrict resource: URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy, as demonstrated by the resource: URL associated with PDF.js. (CVE-2015-0816)
The QCMS implementation in Mozilla Firefox before 37.0 allows remote attackers to obtain sensitive information from process heap memory or cause a denial of service (out-of-bounds read) via an image that is improperly handled during transformation. (CVE-2015-0811)
The webrtc::VPMContentAnalysis::Release function in the WebRTC implementation in Mozilla Firefox before 37.0 uses incompatible approaches to the deallocation of memory for simple-type arrays, which might allow remote attackers to cause a denial of service (memory corruption) via unspecified vectors. (CVE-2015-0808)
The navigator.sendBeacon implementation in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 processes HTTP 30x status codes for redirects after a preflight request has occurred, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site, a similar issue to CVE-2014-8638. (CVE-2015-0807)
The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 makes an incorrect memset call during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors that trigger rendering of 2D graphics content. (CVE-2015-0805)
The Off Main Thread Compositing (OMTC) implementation in Mozilla Firefox before 37.0 attempts to use memset for a memory region of negative length during interaction with the mozilla::layers::BufferTextureClient::AllocateForSurface function, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors that trigger rendering of 2D graphics content. (CVE-2015-0806)
The HTMLSourceElement::AfterSetAttr function in Mozilla Firefox before 37.0 does not properly constrain the original data type of a casted value during the setting of a SOURCE element's attributes, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document. (CVE-2015-0803)
The HTMLSourceElement::BindToTree function in Mozilla Firefox before 37.0 does not properly constrain a data type after omitting namespace validation during certain tree-binding operations, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via a crafted HTML document containing a SOURCE…

firefox vulnerability
Muneaki Nishimura discovered a flaw in Mozilla's HTTP Alternative Services implementation which meant SSL certificate verification could be bypassed in some circumstances. A remote attacker could potentially exploit this to conduct a machine-in-the-middle attack. (CVE-2015-0799)
