CVE-2020-16042: Operations on a BigInt could have caused uninitialized memory to be exposed Impact critical Description When a BigInt was right-shifted the backing store was not properly cleared, allowing uninitialized memory to be read. References CVE-2020-26971: Heap buffer overflow in WebGL Impact high Description Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow on some video drivers. CVE-2020-26973: CSS Sanitizer performed incorrect sanitization Impact high Description Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This could have been used as a sanitizer bypass. CVE-2020-26974: Incorrect cast of StyleGenericFlexBasis resulted in a heap use-after-free Impact high Description When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially exploitable crash. CVE-2020-26978: Internal network hosts could have been probed by a malicious webpage Impact moderate Description Using techniques that built on the slipstream research, a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. CVE-2020-35111: The proxy.onRequest API did not catch view-source URLs Impact low Description When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening View Source could have inadvertently leaked their IP address. CVE-2020-35113: Memory safety bugs fixed in Firefox 84 and Firefox ESR 78.6 Impact high Description Mozilla developer Christian Holler reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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.
