Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Spoofing attack

EUVDB-ID: #VU89895

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-52881

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error within the tcp_ack() function in net/ipv4/tcp_input.c, which can result in system accepting ACK responses for bytes that were never sent. A remote attacker can perform spoofing attack.

Mitigation

2) Race condition

EUVDB-ID: #VU85022

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-2023-6531

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition when the unix garbage collector's deletion of a SKB races with unix_stream_read_generic() on the socket that the SKB is queued on. A local user can exploit the race and escalate privileges on the system.

7) Integer underflow

EUVDB-ID: #VU86552

Risk: High

CVSSv4.0: 5.9 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2024-0565

CWE-ID: CWE-191 - Integer underflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer underflow within the receive_encrypted_standard() function in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. A remote attacker can trick the victim to connect to a malicious SMB server, trigger an integer underflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

8) Out-of-bounds write

EUVDB-ID: #VU86246

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-2024-0646

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when processing untrusted input in the Linux kernel’s Transport Layer Security functionality in the way a user calls a function splice with a ktls socket as the destination. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
