1) CVE-2020-6821 Description: "Uninitialized memory could be read when using the WebGL copyTexSubImage method. When reading from areas partially or fully outside the source resource with WebG L's copyTexSubImage method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure."

On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in GMPDecodeData. It is possible that with enough effort this could have been exploited to run arbitrary code." Bug (restricted): https://bugzilla.mozilla.org/show_bug.cgi?id=1544181 Affects: <68.7, <75 3) CVE-2020-6823 Description: "Malicious Extension could obtain auth codes from OAuth login flows.

Bug (restricted): https://bugzilla.mozilla.org/show_bug.cgi?id=1614919 Affects: <75 4) CVE-2020-6824 Description: "Generated passwords may be identical on the same site between separate private browsing sessions. Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open. Subsequently, if the user had opened a new Private Browsing Window, revisited the same site, and generated a new password - the generated passwords would have been identical, rather than independent." Bug (restricted): https://bugzilla.mozilla.org/show_bug.cgi?id=1621853 Affects: <75 5) CVE-2020-6825 Description: "Memory safety bugs fixed in Firefox 75 and Firefox ESR 68.7. Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. 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."
