CVE-2021-29948 (https://nvd.nist.gov/vuln/detail/CVE-2021-29948): Race condition when reading from disk while verifying signatures. Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. CVE-2021-23961 (https://nvd.nist.gov/vuln/detail/CVE-2021-23961): ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem.

CVE-2021-23994 (https://nvd.nist.gov/vuln/detail/CVE-2021-23994): Out of bound write due to lazy initialization.

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.

CVE-2021-24002 (https://nvd.nist.gov/vuln/detail/CVE-2021-24002): Arbitrary FTP command execution on FTP servers using an encoded URL.

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.
