In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.

The version of lua / ntopng / memcached installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2021-45985 advisory.

  - In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.
    (CVE-2021-45985)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-533 advisory.

    2024-05-09: CVE-2022-33099 was added to this advisory.

    In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.
    (CVE-2021-45985)

    An issue in the component luaG_runerror of Lua v5.4.4 and below leads to a heap-buffer overflow when a     recursive error occurs. (CVE-2022-33099)

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.

According to the versions of the lua package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.
    (CVE-2021-45985)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
