Debian DLA-3469-1 : lua5.3 - LTS security update

high Nessus Plugin ID 177553

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3469 advisory.

- Lua 5.3.5 has a use-after-free in lua_upvaluejoin in lapi.c. For example, a crash outcome might be achieved by an attacker who is able to trigger a debug.upvaluejoin call in which the arguments have certain relationships. (CVE-2019-6706)

- ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal(3,2^31). (CVE-2020-24370)

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

Solution

Upgrade the lua5.3 packages.

For Debian 10 buster, these problems have been fixed in version 5.3.3-1.1+deb10u1.
