"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2022:0058-1 advisory.

  - When receiving an OpenPGP/MIME signed email message that contains an additional outer MIME message layer,
    for example a message footer added by a mailing list gateway, Thunderbird only considered the inner signed
    message for the signature validity. This gave the false impression that the additional contents were also
    covered by the digital signature. Starting with Thunderbird version 91.4.1, only the signature that
    belongs to the top level MIME part will be considered for the displayed status. This vulnerability affects
    Thunderbird < 91.4.1. (CVE-2021-4126)

  - The olm_session_describe function in Matrix libolm before 3.2.7 is vulnerable to a buffer overflow. The
    Olm session object represents a cryptographic channel between two parties. Therefore, its state is
    partially controllable by the remote party of the channel. Attackers can construct a crafted sequence of
    messages to manipulate the state of the receiver's session in such a way that, for some buffer sizes, a
    buffer overflow happens on a call to olm_session_describe. Furthermore, safe buffer sizes were
    undocumented. The overflow content is partially controllable by the attacker and limited to ASCII spaces
    and digits. The known affected products are Element Web And SchildiChat Web. (CVE-2021-44538)

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