| Название | Open5GS v2.7.6 Buffer Over-read |
|---|
| Описание | Open5GS version 2.7.6 suffers from a buffer overread, which has been disclosed and acknowledged by the developers and fixed.
For reproduction, this can be triggered by executing the VoLTE CX Test, like described in the Github Issue (https://github.com/open5gs/open5gs/issues/4177).
The stack buffer ak is logged using OGS_KEY_LEN, but it is allocated with the shorter OGS_AK_LEN. This leads to a stack buffer overread, which is being logged. This mismatch causes a stack buffer over-read during logging, potentially leading to instability or information leakage. This is potentially remotely triggerable. |
