The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0957 advisory.

    The lua packages provide support for Lua, a powerful light-weight programming language designed for     extending applications. Lua is also frequently used as a general-purpose, stand-alone language.

    Security Fix(es):

    * lua: use after free allows Sandbox Escape (CVE-2021-44964)

    * lua: stack overflow in lua_resume of ldo.c allows a DoS via a crafted script file (CVE-2021-43519)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-031 advisory.

    A stack overflow issue was discovered in Lua in the lua_resume() function of ldo.c. This flaw allows a     local attacker to pass a specially crafted file to the Lua Interpreter, causing a crash that leads to a     denial of service. (CVE-2021-43519)

    A flaw was found in Lua. An SEGV crash in the funcnamefromcode() function in ldebug.c during error     handling occurs in __close metamethods. This flaw allows an attacker to cause a denial of service.
    (CVE-2021-44647)

An update of the nmap package has been released.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-176 advisory.

    A stack overflow issue was discovered in Lua in the lua_resume() function of ldo.c. This flaw allows a     local attacker to pass a specially crafted file to the Lua Interpreter, causing a crash that leads to a     denial of service. (CVE-2021-43519)

    (CVE-2021-44647)

    A heap buffer-overflow vulnerability was found in Lua. The flaw occurs due to vulnerable code present in     the lparser.c function of Lua that allows the execution of untrusted Lua code into a system, resulting in     malicious activity. (CVE-2022-28805)

    A vulnerability was found in Lua. During error handling, the luaG_errormsg() component uses slots from     EXTRA_STACK. Some errors can recur such as a string overflow while creating an error message in     luaG_runerror, or a C-stack overflow before calling the message handler, causing a crash that leads to a     denial of service.
