Synopsis

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

Description

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-55611 advisory.

- Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow on some video drivers. (CVE-2020-26971)

- Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This could have been used as a sanitizer bypass. (CVE-2020-26973)

- 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)

- 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-2020-26978)

- 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 firefox package.
