Double free vulnerability in the ResourceFetcher::didLoadResource function in core/fetch/ResourceFetcher.cpp in the resource loader in Blink, as used in Google Chrome before 30.0.1599.66, allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering certain callback processing during the reporting of a resource entry.

Multiple race conditions in the Web Audio implementation in Blink, as used in Google Chrome before 30.0.1599.66, allow remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to threading in core/html/HTMLMediaElement.cpp, core/platform/audio/AudioDSPKernelProcessor.cpp, core/platform/audio/HRTFElevation.cpp, and modules/webaudio/ConvolverNode.cpp.

The DoResolveRelativeHost function in url/url_canon_relative.cc in Google Chrome before 30.0.1599.66 allows remote attackers to cause a denial of service (out-of-bounds read) via a relative URL containing a hostname, as demonstrated by a protocol-relative URL beginning with a //www.google.com/ substring.
