Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU81661
Risk: Medium
CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-3865
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the ksmbd_smb2_check_message() function in fs/smb/server/smb2misc.c when parsing smb2_hdr structure. A remote user can send specially crafted packets to ksmbd, trigger an out-of-bounds read error and read contents of memory or perform a denial of service (DoS) attack.
Install updates from vendor's repository.

EUVDB-ID: #VU81662
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-3866
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the void __handle_ksmbd_work() function in fs/smb/server/server.c when handling chained requests. A remote attacker can send specially crafted data to the ksmbd and perform a denial of service (DoS) attack.

EUVDB-ID: #VU79487
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-4273
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
