FreeBSD : redis,valkey -- Out of bound read due to a bug in LUA (0af2f18e-a119-11f0-9446-f02f7497ecda)

medium Nessus Plugin ID 266599

Language:

Synopsis

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

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 0af2f18e-a119-11f0-9446-f02f7497ecda advisory.

 redis reports:

 An authenticated user may use a specially crafted LUA script to read out-of-bound data or crash the server and subsequent denial of service.
 The problem exists in all versions of Redis with Lua scripting An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to block a script by restricting both the EVAL and FUNCTION command families.


Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

Solution

Update the affected packages.
