The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:14782-1 advisory.

  - Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption     and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91,     Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29980)

  - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly     considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
    This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29984)

  - A use-after-free vulnerability in media channels could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29985)

  - A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable     crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.*     This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29986)

  - Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds     read or memory corruption, and a potentially exploitable crash. This vulnerability affects Thunderbird <     78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29988)

  - Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. 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. This vulnerability affects Thunderbird < 78.13, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29989)

The version of thunderbird installed on the remote host is prior to 78.13.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1709 advisory.

    If Thunderbird was configured to use STARTTLS for an IMAP connection, and an attacker injected IMAP server     responses prior to the completion of the STARTTLS handshake, then Thunderbird didn't ignore the injected     data. This could have resulted in Thunderbird showing incorrect information, for example the attacker     could have tricked Thunderbird to show folders that didn't exist on the IMAP server. This vulnerability     affects Thunderbird < 78.12. (CVE-2021-29969)

    A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially     exploitable crash. *This bug could only be triggered when accessibility was enabled.*. This vulnerability     affects Thunderbird < 78.12, Firefox ESR < 78.12, and Firefox < 90. (CVE-2021-29970)
