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-2021-3157 advisory.

- Mozilla: Uninitialized memory in a canvas object could have led to memory corruption (CVE-2021-29980)

- Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
(CVE-2021-29984)

- A use-after-free vulnerability in media channels could have led to memory corruption and a potentially exploitable crash. (CVE-2021-29985)

- A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable crash. Note: This issue only affected Linux operating systems. Other operating systems are unaffected. (CVE-2021-29986)

- Thunderbird incorrectly treated an inline list-item element as a block element, resulting in an out of bounds read or memory corruption, and a potentially exploitable crash. (CVE-2021-29988)

- Mozilla developers Christoph Kerschbaumer, Simon Giesecke, Sandor Molnar, and Olli Pettay reported memory safety bugs present in Thunderbird 78.12. 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-2021-29989)

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.
