Alpine: multiple firefox-esr packages: security update to 68.4.1-r0

high Tenable Self-Hosted Container Security Plugin ID 404430

Description

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

- When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly
rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in
data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17016)

- When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not
escape < and > characters. Because the resulting string is pasted directly into the text node of the
element this does not result in a direct injection into the webpage; however, if a webpage subsequently
copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability.
Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox
ESR < 68.4 and Firefox < 72. (CVE-2019-17022)

- Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. 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 < 68.4 and Firefox < 72.
(CVE-2019-17024)

- Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type
confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects
Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1. (CVE-2019-17026)
