Summary

The Bdat driver of Prague smart phones with software versions earlier than Prague-AL00AC00B211, versions earlier than Prague-AL00BC00B211, versions earlier than Prague-AL00CC00B211, versions earlier than Prague-TL00AC01B211, versions earlier than Prague-TL10AC01B211 has integer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP and execute it as a specific privilege; the APP can then send a specific parameter to the driver of the smart phone, causing arbitrary code execution.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
