"The version of thunderbird installed on the remote host is prior to 128.8.1-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2025-2830 advisory.

    There exists an out of bounds read/write in LibJXL versions prior to commit
    9cc451b91b74ba470fd72bd48c121e9f33d24c99. The JPEG decoder used by the JPEG XL encoder when doing JPEG
    recompression (i.e. if using JxlEncoderAddJPEGFrame on untrusted input) does not properly check bounds in
    the presence of incomplete codes. This could lead to an out-of-bounds write. In jpegli which is released
    as part of the same project, the same vulnerability is present. However, the relevant buffer is part of a
    bigger structure, and the code makes no assumptions on the values that could be overwritten. The issue
    could however cause jpegli to read uninitialised memory, or addresses of functions. (CVE-2024-11403)

    An issue was discovered in libexpat before 2.6.4. There is a crash within the XML_ResumeParser function
    because XML_StopParser can stop/suspend an unstarted parser. (CVE-2024-50602)

    oc_huff_tree_unpack in huffdec.c in libtheora in Theora through 1.0 7180717 has an invalid negative left
    shift. (CVE-2024-56431)

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

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