We would also like to thank all security researchers that worked with us during the development cycle to prevent security bugs from ever reaching the stable channel. The total value of additional rewards and their recipients will updated here when all reports have gone through the reward panel. As usual, our ongoing internal security work was responsible for a wide range of fixes: [476786] CVE-2015-1249: Various fixes from internal audits, fuzzing and other initiatives. Multiple vulnerabilities in V8 fixed at the tip of the 4.2 branch (currently 4.2.77.14). @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
chromium-42.0.2311.90 is in the tree. Please stabilize for amd64 and x86.
amd64 stable
x86 stable. Maintainer(s), please cleanup. Security, please add it to the existing request, or file a new one.
Arches and Maintainer(s), Thank you for your work. Added to an existing GLSA Request.
CVE-2015-1248 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1248): The FileSystem API in Google Chrome before 40.0.2214.91 allows remote attackers to bypass the SafeBrowsing for Executable Files protection mechanism by creating a .exe file in a temporary filesystem and then referencing this file with a filesystem:http: URL. CVE-2015-1247 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1247): The SearchEngineTabHelper::OnPageHasOSDD function in browser/ui/search_engines/search_engine_tab_helper.cc in Google Chrome before 42.0.2311.90 does not prevent use of a file: URL for an OpenSearch descriptor XML document, which might allow remote attackers to obtain sensitive information from local files via a crafted (1) http or (2) https web site. CVE-2015-1246 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1246): Blink, as used in Google Chrome before 42.0.2311.90, allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors. CVE-2015-1245 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1245): Use-after-free vulnerability in the OpenPDFInReaderView::Update function in browser/ui/views/location_bar/open_pdf_in_reader_view.cc in Google Chrome before 41.0.2272.76 might allow user-assisted remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact by triggering interaction with a PDFium "Open PDF in Reader" button that has an invalid tab association. CVE-2015-1244 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1244): The URLRequest::GetHSTSRedirect function in url_request/url_request.cc in Google Chrome before 42.0.2311.90 does not replace the ws scheme with the wss scheme whenever an HSTS Policy is active, which makes it easier for remote attackers to obtain sensitive information by sniffing the network for WebSocket traffic. CVE-2015-1242 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1242): The ReduceTransitionElementsKind function in hydrogen-check-elimination.cc in Google V8 before 4.2.77.8, as used in Google Chrome before 42.0.2311.90, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that leverages "type confusion" in the check-elimination optimization. CVE-2015-1241 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1241): Google Chrome before 42.0.2311.90 does not properly consider the interaction of page navigation with the handling of touch events and gesture events, which allows remote attackers to trigger unintended UI actions via a crafted web site that conducts a "tapjacking" attack. CVE-2015-1240 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1240): gpu/blink/webgraphicscontext3d_impl.cc in the WebGL implementation in Google Chrome before 42.0.2311.90 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted WebGL program that triggers a state inconsistency. CVE-2015-1238 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1238): Skia, as used in Google Chrome before 42.0.2311.90, allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via unknown vectors. CVE-2015-1237 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1237): Use-after-free vulnerability in the RenderFrameImpl::OnMessageReceived function in content/renderer/render_frame_impl.cc in Google Chrome before 42.0.2311.90 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger renderer IPC messages during a detach operation. CVE-2015-1236 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1236): The MediaElementAudioSourceNode::process function in modules/webaudio/MediaElementAudioSourceNode.cpp in the Web Audio API implementation in Blink, as used in Google Chrome before 42.0.2311.90, allows remote attackers to bypass the Same Origin Policy and obtain sensitive audio sample values via a crafted web site containing a media element. CVE-2015-1235 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2015-1235): The ContainerNode::parserRemoveChild function in core/dom/ContainerNode.cpp in the HTML parser in Blink, as used in Google Chrome before 42.0.2311.90, allows remote attackers to bypass the Same Origin Policy via a crafted HTML document with an IFRAME element.
