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 ALAS2-2025-2807 advisory.

    Requests initiated through reader mode did not properly omit cookies with a SameSite attribute. This     vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100. (CVE-2022-29912)

    The parent process would not properly check whether the Speech Synthesis feature is enabled, when     receiving instructions from a child process. This vulnerability affects Thunderbird < 91.9.
    (CVE-2022-29913)

    In resizeToAtLeast of SkRegion.cpp, there is a possible out of bounds write due to an integer overflow.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation. (CVE-2024-43097)

    It was possible to cause a use-after-free in the content process side of a WebTransport connection,     leading to a potentially exploitable crash. This vulnerability affects Firefox < 136, Firefox ESR <     115.21, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8. (CVE-2025-1931)

    An inconsistent comparator in xslt/txNodeSorter could have resulted in potentially exploitable out-of-     bounds access. Only affected version 122 and later. This vulnerability affects Firefox < 136, Firefox ESR     < 128.8, Thunderbird < 136, and Thunderbird < 128.8. (CVE-2025-1932)

    On 64-bit CPUs, when the JIT compiles WASM i32 return values they can pick up bits from left over memory.
    This can potentially cause them to be treated as a different type. This vulnerability affects Firefox <     136, Firefox ESR < 115.21, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8.
    (CVE-2025-1933)

    It was possible to interrupt the processing of a RegExp bailout and run additional JavaScript, potentially     triggering garbage collection when the engine was not expecting it. This vulnerability affects Firefox <     136, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8. (CVE-2025-1934)

    A web page could trick a user into setting that site as the default handler for a custom URL protocol.
    This vulnerability affects Firefox < 136, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8.
    (CVE-2025-1935)

    jar: URLs retrieve local file content packaged in a ZIP archive. The null and everything after it was     ignored when retrieving the content from the archive, but the fake extension after the null was used to     determine the type of content. This could have been used to hide code in a web extension disguised as     something else like an image. This vulnerability affects Firefox < 136, Firefox ESR < 128.8, Thunderbird <     136, and Thunderbird < 128.8. (CVE-2025-1936)

    Memory safety bugs present in Firefox 135, Thunderbird 135, Firefox ESR 115.20, Firefox ESR 128.7, and     Thunderbird 128.7. 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 Firefox <     136, Firefox ESR < 115.21, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8.

This vulnerability affects Firefox < 136, Firefox ESR <     128.8, Thunderbird < 136, and Thunderbird < 128.8. (CVE-2025-1938)

    When requesting an OpenPGP key from a WKD server, an incorrect padding size was used and a network     observer could have learned the length of the requested email address. This vulnerability affects     Thunderbird < 136 and Thunderbird < 128.8. (CVE-2025-26695)

    Certain crafted MIME email messages that claimed to contain an encrypted OpenPGP message, which instead     contained an OpenPGP signed message, were wrongly shown as being encrypted. This vulnerability affects     Thunderbird < 136 and Thunderbird < 128.8. (CVE-2025-26696)
