Summary:	Mozilla Thunderbird is prone to multiple vulnerabilities.
Description:	Summary: Mozilla Thunderbird is prone to multiple vulnerabilities. Vulnerability Insight: Multiple flaws exist due to: - Operations on a BigInt could have caused uninitialized memory to be exposed. - Heap buffer overflow in WebGL. - CSS Sanitizer performed incorrect sanitization. - Incorrect cast of StyleGenericFlexBasis resulted in a heap use-after-free. - Internal network hosts could have been probed by a malicious webpage. - The proxy.onRequest API did not catch view-source URLs. - Opening an extension-less download may have inadvertently launched an executable instead. - Memory safety bugs fixed in Thunderbird 78.6. Vulnerability Impact: Successful exploitation will allow attackers to conduct a denial-of-service, execute arbitrary code or information disclosure on affected system. Affected Software/OS: Mozilla Thunderbird version before 78.6. Solution: Update to Mozilla Thunderbird version 78.6 or later. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
