Mozilla developers reported memory safety bugs present in Firefox 86. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 87.
2	CVE-2021-23987	119	Overflow Mem. Corr.	2021-03-31	2021-06-04	6.8	None	Remote	Medium	Not required	Partial	Partial	Partial
Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR 78.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.9, Thunderbird < 78.9, and Firefox < 87.
3	CVE-2021-23986	346	Bypass	2021-03-31	2021-06-04	4.3	None	Remote	Medium	Not required	Partial	None	None
A malicious extension with the 'search' permission could have installed a new search engine whose favicon referenced a cross-origin URL. The response to this cross-origin request could have been read by the extension, allowing a same-origin policy bypass by the extension, which should not have cross-origin permissions. This cross-origin request was made without cookies, so the sensitive information disclosed by the violation was limited to local-network resources or resources that perform IP-based authentication. This vulnerability affects Firefox < 87.
4	CVE-2021-23985	668		2021-03-31	2021-06-04	4.3	None	Remote	Medium	Not required	Partial	None	None
If an attacker is able to alter specific about:config values (for example malware running on the user's computer), the Devtools remote debugging feature could have been enabled in a way that was unnoticable to the user. This would have allowed a remote attacker (able to make a direct network connection to the victim) to monitor the user's browsing activity and (plaintext) network traffic. This was addressed by providing a visual cue when Devtools has an open network socket. This vulnerability affects Firefox < 87.
5	CVE-2021-23984	290		2021-03-31	2021-06-04	4.3	None	Remote	Medium	Not required	None	Partial	None

17	CVE-2021-23969			2021-02-26	2021-05-01	4.3	None	Remote	Medium	Not required	Partial	None	None
As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
18	CVE-2021-23968	209	+Info	2021-02-26	2021-05-01	4.3	None	Remote	Medium	Not required	Partial	None	None
If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
19	CVE-2021-23965	119	Overflow Mem. Corr.	2021-02-26	2021-03-04	6.8	None	Remote	Medium	Not required	Partial	Partial	Partial
