Summary

libosmo-sigtran through 2.2.1 contains an out-of-bounds read in the M3UA NOTIFY decoder in src/m3ua.c. This allows a remote attacker to obtain sensitive information.

Risk Assessment

A remote attacker could exploit this vulnerability to leak data from process memory, potentially exposing sensitive information. This may lead to a breach of communication confidentiality.

Recommendation

Update libosmo-sigtran to a version later than 2.2.1 that contains the fix. Until then, restrict access to services using this library.
