Oracle Linux 7 : firefox (ELSA-2021-0992)

high Nessus Plugin ID 148127

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-2021-0992 advisory.

- A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash.
(CVE-2021-23981)

- Mozilla: Internal network hosts could have been probed by a malicious webpage (CVE-2021-23982)

- A malicious extension could have opened a popup window lacking an address bar. The title of the popup lacking an address bar should not be fully controllable, but in this situation was. This could have been used to spoof a website and attempt to trick the user into providing credentials. (CVE-2021-23984)

- Mozilla developers and community members Alexis Beingessner, Tyson Smith, Julien Wajsberg, and Matthew Gregan reported memory safety bugs present in Thunderbird 78.8. 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-2021-23987)

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.
