Name of the Vulnerable Software and Affected Versions oFono (affected versions not specified)

Description A flaw in the oFono interface for working with mobile connectivity is related to a buffer overflow in the decode deliver() function during SMS decoding. This issue can be exploited by a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The attack scenario is assumed to be accessible from a compromised modem, a malicious base station, or via SMS. A bound check for the memcpy length in decode submit() was forgotten in decode deliver(), leading to the stack overflow bug.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
