Test ID:	1.3.6.1.4.1.25623.1.0.104696
Category:	Denial of Service
Title:	OpenSSL 3.0 <= 3.0.8, 3.1.0 DoS Vulnerability
Summary:	OpenSSL is prone to a denial of service (DoS) vulnerability.
Description:	Summary: OpenSSL is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that could cause it to read past the input buffer, leading to a crash. Vulnerability Impact: Applications that use the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g. 144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash which results in a denial of service. If an attacker can control the size and location of the ciphertext buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is fairly unlikely making this issue a Low severity one. Affected Software/OS: OpenSSL versions 3.0.0 through 3.0.8 and 3.1.0 on 64 bit ARM platforms. Solution: Update to version 3.0.9, 3.1.1 or later. CVSS Score: 5.4 CVSS Vector: AV:N/AC:H/Au:N/C:N/I:N/A:C
