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

Description This issue allows local attackers to execute arbitrary code on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this issue. The specific flaw exists within the parsing of STK command PDUs. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this issue to execute code in the context of the service account.

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