Synopsis

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

Description

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

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 --releasever=2022.0.20220222 lua' to update your system.
