CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2020-14382 – cryptsetup: Out-of-bounds write when validating segments
https://notcve.org/view.php?id=CVE-2020-14382
A vulnerability was found in upstream release cryptsetup-2.2.0 where, there's a bug in LUKS2 format validation code, that is effectively invoked on every device/image presenting itself as LUKS2 container. The bug is in segments validation code in file 'lib/luks2/luks2_json_metadata.c' in function hdr_validate_segments(struct crypt_device *cd, json_object *hdr_jobj) where the code does not check for possible overflow on memory allocation used for intervals array (see statement "intervals = malloc(first_backup * sizeof(*intervals));"). Due to the bug, library can be *tricked* to expect such allocation was successful but for far less memory then originally expected. Later it may read data FROM image crafted by an attacker and actually write such data BEYOND allocated memory. Se encontró una vulnerabilidad en la versión previa cryptsetup-2.2.0 donde se presenta un error en el código de comprobación del formato LUKS2, que es invocado efectivamente en cada dispositivo e imagen que se presenta como contenedor de LUKS2. • https://bugzilla.redhat.com/show_bug.cgi?id=1874712 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OJTQ4KSVCW2NMSU5WFVPOHY46WMNF4OB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TD6YSD63LLRRC4WQ7DJLSXWNUCY6FWBM https://usn.ubuntu.com/4493-1 https://access.redhat.com/security/cve/CVE-2020-14382 • CWE-787: Out-of-bounds Write •
