Title
aligungr UERANSIM Radio Link Simulation Layer rls_pdu.cpp DecodeRlsMessage uncaught exception
Summary
A vulnerability has been found in aligungr UERANSIM up to 3.2.7. The affected element is the function rls::DecodeRlsMessage in the library src/lib/rls/rls_pdu.cpp of the component Radio Link Simulation Layer. The manipulation of the argument pduLength leads to uncaught exception. The attack may be initiated remotely. Upgrading to version 3.2.8 is sufficient to fix this issue. The identifier of the patch is ca1a66fffe282767bb08618af9f848e3b68ea47b. It is suggested to upgrade the affected component. This behavior is related to CVE-2024-37877. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
