Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-3711)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in EVP_PKEY_decrypt() function within implementation of the SM2 decryption. A remote attacker can send specially crafted SM2 content for decryption to trigger a buffer overflow by 62 bytes and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Out-of-bounds read (CVE-ID: CVE-2021-3712)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.


3) Race condition (CVE-ID: CVE-2020-8670)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition in the firmware . A local administrator can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.


4) Input validation error (CVE-ID: CVE-2021-30004)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to insufficient validation of user-supplied input in tls/pkcs1.c and tls/x509v3.c files in wpa_supplicant and hostapd when handling AlgorithmIdentifier parameters. A remote attacker can pass specially crafted input to the application and perform MitM attack.


5) Out-of-bounds write (CVE-ID: CVE-2021-38578)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in MdeModulePkg/Core/PiSmmCore/PiSmmCore.c. A local user trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
