WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4122-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to obtain sensitive information, bypass     Content Security Policy (CSP) protections, bypass same-origin restrictions, conduct cross-site scripting     (XSS) attacks, cause a denial of service, or execute arbitrary code. (CVE-2019-5849, CVE-2019-11734,     CVE-2019-11735, CVE-2019-11737, CVE-2019-11738, CVE-2019-11740, CVE-2019-11742, CVE-2019-11743,     CVE-2019-11744, CVE-2019-11746, CVE-2019-11748, CVE-2019-11749, CVE-2019-11750, CVE-2019-11752)

    It was discovered that a compromised content process could log in to a malicious Firefox Sync account. An     attacker could potentially exploit this, in combination with another vulnerability, to disable the     sandbox. (CVE-2019-9812)

    It was discovered that addons.mozilla.org and accounts.firefox.com could be loaded in to the same content     process. An attacker could potentially exploit this, in combination with another vulnerability that     allowed a cross-site scripting (XSS) attack, to modify browser settings. (CVE-2019-11741)

    It was discovered that the Forget about this site feature in the history pane removes HTTP Strict     Transport Security (HSTS) settings for sites on the pre-load list. An attacker could potentially exploit     this to bypass the protections offered by HSTS. (CVE-2019-11747)
