The AES-XTS algorithm is usually\nused for disk encryption.\n\nThe AES-XTS cipher decryption implementation for 64 bit ARM platform will read\npast the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16\nbyte blocks, e.g. 144 bytes or 1024 bytes. If the memory after the ciphertext\nbuffer is unmapped, this will trigger a crash which results in a denial of\nservice.\n\nIf an attacker can control the size and location of the ciphertext buffer\nbeing decrypted by an application using AES-XTS on 64 bit ARM, the\napplication is affected. This is fairly unlikely making this issue\na Low severity one."}], "lastModified": "2023-09-08T17:15:15.800", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4C637E94-F5EC-4D4B-836F-8C8219F1ECEC", "versionEndExcluding": "3.0.9", "versionStartIncluding": "3.0.0"}, {"criteria": "cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "68821BE0-7889-48B0-888D-CEC8BB9BDEA9", "versionEndExcluding": "3.1.1", "versionStartIncluding": "3.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "openssl-security@openssl.org"}
