CVE-2021-4122 1 Cryptsetup Project 1 Cryptsetup 2023-12-10 N/A 4.3 MEDIUM
It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.
CVE-2020-14382 4 Canonical, Cryptsetup Project, Fedoraproject and 1 more 4 Ubuntu Linux, Cryptsetup, Fedora and 1 more 2023-12-10 6.8 MEDIUM 7.8 HIGH
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.
CVE-2016-4484 1 Cryptsetup Project 1 Cryptsetup 2023-12-10 7.2 HIGH 6.8 MEDIUM
The Debian initrd script for the cryptsetup package 2:1.7.3-2 and earlier allows physically proximate attackers to gain shell access via many log in attempts with an invalid password.
