Alpine: multiple firefox-esr packages: security update to 78.9.0-r0

high Tenable Cloud Security Plugin ID 404452

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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.
This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23981)

- Using techniques that built on the slipstream research, a malicious webpage could have scanned both an
internal network's hosts as well as services running on the user's local machine utilizing WebRTC
connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.
(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. This vulnerability
affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23984)

- Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR
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. This vulnerability affects Firefox ESR < 78.9,
Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23987)
