This applies commit 02ac9c94 to fix this OpenSSL Security Advisory issued on 20th April 2023[1]: Input buffer over-read in AES-XTS implementation on 64 bit ARM (CVE-2023-1255) ============================================================== Severity: Low Issue summary: 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. Impact summary: 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. 1. https://www.openssl.org/news/secadv/20230420.txt Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com> |
