Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4936-1 advisory.

 Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, or execute arbitrary code. (CVE-2021-23968, CVE-2021-23969, CVE-2021-23973, CVE-2021-23978)

 It was discovered that Thunderbird may keep key material in memory in some circumstances. A local attacker could potentially exploit this to obtain private keys. (CVE-2021-29950)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
