Summary

osmo-msc through 1.15.0 contains a stack-based buffer overflow in decode_mme_name() in src/libmsc/sgs_iface.c. This allows a remote attacker to cause a denial of service.

Risk Assessment

A remote attacker could exploit the stack-based buffer overflow to cause a crash or instability of the osmo-msc service. This may result in unavailability of telecommunications services relying on this component.

Recommendation

Update osmo-msc to a version later than 1.15.0 that contains the fix. Until then, restrict access to SGs interfaces from untrusted networks.
