The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2022-6164 advisory.

  • Members the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.1 and Thunderbird 91.12. 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-2022-38478)

  • An attacker could have abused XSLT error handling to associate attacker-controlled content with another origin which was displayed in the address bar. This could have been used to fool the user into submitting data intended for the spoofed origin. (CVE-2022-38472)

  • Mozilla: Cross-origin XSLT Documents would have inherited the parent’s permissions (CVE-2022-38473)

  • A data race could occur in the <code>PK11ChangePW</code> function, potentially leading to a use-after-free vulnerability. In Thunderbird, this lock protected the data when a user changed their master password.
    (CVE-2022-38476)

  • Mozilla developer Nika Layzell and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.1. 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-2022-38477)

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