Summary

The BL1 FWU SMC handling code in ARM Trusted Firmware before 1.4 might allow attackers to write arbitrary data to secure memory, bypass the bl1_plat_mem_check protection mechanism, cause a denial of service, or possibly have unspecified other impact via a crafted AArch32 image, which triggers an integer overflow.

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.
