Technical details
Vulnerability (2) related to implementation error with unboxed objects and property storing. This vulnerability can be triggered during some Javascript variables assignment.
Vulnerability (3) can be triggered if perfomance.getEntries() is used with iframe to host a page. This vulnerability could lead to cross-origin URLs following (Navigating back through script , content is pulled from browser cache for the redirected location instead original)
Vulnerability (4) caused by storing ASCII code 11 for vertical tab at cookie in violation of RFC6265. This vulnerability can lead to incorrect server-side cookie handling which in its turn can lead to ability of setting and reading cookie data.
Vulnerability (5) related to timing issues that causes WebRTC to trust that datachannel is open after another WebRTC function closed it.
Vulnerability (6) emerges when allocating textures of extremely large sizes at mozilla::layers::BufferTextureClient::AllocateForSurface.
Vulnerability (7) leaks information through error events in web workers. This information could be used to gain authentication tokens and other data.
Vulnerability (8) caused by improper ‘#’ symbol handling at data: URI which can lead to spoof URI.
Vulnerability (9) can be triggered via malformed HTTP2 header frame with only a single byte or HTTP2 PushPromise frame with miscalculation of decompressed buffer size.
Vulnerability (10) caused by using system’s gdk-pixbuf library to render thumbnails for file choose dialog. Some of image decoders (Jasper and TGA) supported in this library unmantained and vulnerable. This vulnerability affects only Linux systems with Gnome.
Vulnerability (11) related to OOM in DirectWriteFontInfo::LoadFontFamilyData, XDRBuffer::grow and nsDeque::GrowCapacity.
Vulnerability (12) related to RTPReceiverVideo::ParseRtpPacket.
Vulnerability (13) related to MPEG4Extractor::readMetaData.
Vulnerability (14) related to libstagefright and can be triggered while parsing MP4 cover metadata in Metadata::setData.
Vulnerability (16) can be triggered via data: and view-source: URIs and can lead to read cross-site URLs and local files.
