CVE-2021-23994 (https://nvd.nist.gov/vuln/detail/CVE-2021-23994):
  Out of bound write due to lazy initialization. A WebGL framebuffer was not
  initialized early enough, resulting in memory corruption and an out of bound
  write.

CVE-2021-23995 (https://nvd.nist.gov/vuln/detail/CVE-2021-23995):
  Use-after-free in Responsive Design Mode. When Responsive Design Mode was
  enabled, it used references to objects that were previously freed. We
  presume that with enough effort this could have been exploited to run
  arbitrary code.

CVE-2021-23998 (https://nvd.nist.gov/vuln/detail/CVE-2021-23998):
  Secure Lock icon could have been spoofed. Through complicated navigations
  with new windows, an HTTP page could have inherited a secure lock icon from
  an HTTPS page.

CVE-2021-23999 (https://nvd.nist.gov/vuln/detail/CVE-2021-23999):
  Blob URLs may have been granted additional privileges. If a Blob URL was
  loaded through some unusual user interaction, it could have been loaded by
  the System Principal and granted additional privileges that should not be
  granted to web content.

CVE-2021-24002 (https://nvd.nist.gov/vuln/detail/CVE-2021-24002):
  Arbitrary FTP command execution on FTP servers using an encoded URL. When a
  user clicked on an FTP URL containing encoded newline characters (%0A and
  %0D), the newlines would have been interpreted as such and allowed arbitrary
  commands to be sent to the FTP server.

CVE-2021-29945 (https://nvd.nist.gov/vuln/detail/CVE-2021-29945):
  Incorrect size computation in WebAssembly JIT could lead to null-reads. The
  WebAssembly JIT could miscalculate the size of a return type, which could
  lead to a null read and result in a crash.
  
  Note: This issue only affected x86-32 platforms. Other platforms are
  unaffected.

CVE-2021-29946 (https://nvd.nist.gov/vuln/detail/CVE-2021-29946):
  Port blocking could be bypassed. Ports that were written as an integer
  overflow above the bounds of a 16-bit integer could have bypassed port
  blocking restrictions when used in the Alt-Svc header.
