Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

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)

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)

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. (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.

Solution

Run 'dnf update lua --releasever=2022.0.20221102' to update your system.
