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. 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-2021-24002 (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-2021-23999 (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-2021-23998 (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-2021-23995 (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-2021-23994 (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-2021-23961: More internal network hosts could have been probed by a malicious webpage Impact moderate Description Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine.
I'll re-create this bug.
