{"id":"ALPINE-CVE-2023-1255","details":"Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM\nplatform contains a bug that could cause it to read past the input buffer,\nleading to a crash.\n\nImpact summary: Applications that use the AES-XTS algorithm on the 64 bit ARM\nplatform can crash in rare circumstances. 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.","modified":"2025-12-03T22:51:44.316240Z","published":"2023-04-20T17:15:06.883Z","upstream":["CVE-2023-1255"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-1255"}],"affected":[{"package":{"name":"openssl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.8-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.0.8-r2","3.0.8-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.0-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.0-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.0-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.0-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1.1c-r1","1.1.1d-r1","1.1.1d-r2","1.1.1d-r3","1.1.1d-r4","1.1.1d-r5","1.1.1e-r0","1.1.1f-r0","1.1.1g-r0","1.1.1h-r0","1.1.1i-r0","1.1.1j-r0","1.1.1k-r0","1.1.1k-r1","1.1.1l-r0","3.0.0-r0","3.0.0-r1","3.0.0-r2","3.0.0-r3","3.0.0-r4","3.0.1-r0","3.0.1-r1","3.0.2-r0","3.0.3-r0","3.0.5-r0","3.0.5-r1","3.0.5-r2","3.0.5-r3","3.0.6-r0","3.0.7-r0","3.0.7-r1","3.0.7-r2","3.0.8-r0","3.0.8-r1","3.1.0-r0","3.1.0-r1","3.1.0-r2","3.1.0-r3"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-1255.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.0-r4"}]}],"versions":["1.1.1-r0","1.1.1-r1","1.1.1-r2","1.1.1-r3","1.1.1-r4","1.1.1-r5","1.1.1a-r0","1.1.1a-r1","1.1.1b-r0","1.1.1b-r1","1.1.1c-r0","1.1
