Oracle Linux 8 : ELSA-2020-5624-1: / thunderbird (ELSA-2020-56241)

high Nessus Plugin ID 144457

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-56241 advisory.

- Mozilla: Heap buffer overflow in WebGL (CVE-2020-26971)

- Mozilla: CSS Sanitizer performed incorrect sanitization (CVE-2020-26973)

- When an extension with the proxy permission registered to receive <allurls>, 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-2020-35111)

- Uninitialized Use in V8. (CVE-2020-16042)

- 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-2020-26974)

- Mozilla: Internal network hosts could have been probed by a malicious webpage (CVE-2020-26978)

- 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. (CVE-2020-35113)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected thunderbird package.
