EUVDB-ID: #VU68701
Risk: Low
CVSSv3.1: 3.7 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-3437
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. A remote user can send specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.

EUVDB-ID: #VU81872
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-4091
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote user to truncate read-only files.
The vulnerability exists due to an error in the way SMB protocol implementation in Samba handles file operations. A remote user can request read-only access to files and then truncate them to 0 bytes by opening files with OVERWRITE disposition when using the acl_xattr Samba VFS module with the smb.conf setting "acl_xattr:ignore system acls = yes".

EUVDB-ID: #VU78574
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-34966
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when parsing Spotlight mdssvc RPC packets. A remote attacker can consume all available system resources and cause denial of service conditions on servers where Spotlight is explicitly enabled globally or on individual shares with "spotlight = yes".
