A flaw was found in the GNOME Control Center in Red Hat Enterprise Linux 8 versions prior to 8.2, where it improperly uses Red Hat Customer Portal credentials when a user registers a system through the GNOME Settings User Interface. This flaw allows a local attacker to discover the Red Hat Customer Portal password. The highest threat from this vulnerability is to confidentiality. | |||||
CVE-2020-14383 | 2 Redhat, Samba | 2 Enterprise Linux, Samba | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not. | |||||
CVE-2020-14382 | 4 Canonical, Cryptsetup Project, Fedoraproject and 1 more | 4 Ubuntu Linux, Cryptsetup, Fedora and 1 more | 2024-11-21 | 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-2020-14373 | 2 Artifex, Redhat | 2 Ghostscript, Enterprise Linux | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
