Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Improper Handling of Length Parameter Inconsistency (CVE-ID: CVE-2022-40757)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of length value in TEE_MACComputeFinal function. A remote attacker can invoke the function TEE_MACComputeFinal with an excessive size value of messageLen and cause a denial of service condition on the target system.


2) Uncontrolled Memory Allocation (CVE-ID: CVE-2022-40762)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a memory allocation with excessive size value in the TEE_Realloc function. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


3) Input validation error (CVE-ID: CVE-2022-40761)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the utee_cryp_obj_alloc function. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


4) Improper Handling of Length Parameter Inconsistency (CVE-ID: CVE-2022-40760)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of length value in TEE_MACUpdate, TEE_MACComputeFinal and TEE_CipherUpdate functions. A remote attacker can invoke the function TEE_MACUpdate with an excessive size value of chunkSize and cause a denial of service condition on the target system.


5) NULL pointer dereference (CVE-ID: CVE-2022-40759)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the TEE_MACCompareFinal function. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


6) Improper Handling of Length Parameter Inconsistency (CVE-ID: CVE-2022-40758)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of length value in TEE_CipherUpdate function. A remote attacker can invoke the function TEE_CipherUpdate with an excessive size value of srcLen and cause a denial of service condition on the target system.
