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-2021-0298 advisory.

- When a HTTPS pages was embedded in a HTTP page, and there was a service worker registered for the former, the service worker could have intercepted the request for the secure page despite the iframe not being a secure context due to the (insecure) framing. This vulnerability affects Firefox < 84. (CVE-2020-26976)

- Mozilla developers Alexis Beingessner, Christian Holler, Andrew McCreight, Tyson Smith, Jon Coppeard, Andr Bargull, Jason Kratzer, Jesse Schwartzentruber, Steve Fink, Byron Campen reported memory safety bugs present in Thunderbird 78.6. 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. (CVE-2021-23964)

- If a user clicked into a specifically crafted PDF, the PDF reader could be confused into leaking cross- origin information, when said information is served as chunked data. (CVE-2021-23953)

- Mozilla: Type confusion when using logical assignment operators in JavaScript switch statements (CVE-2021-23954)

- Mozilla: IMAP Response Injection when using STARTTLS (CVE-2020-15685)

- Mozilla: Use-after-poison for incorrectly redeclared JavaScript variables during GC (CVE-2021-23960)

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