Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Type Confusion
EUVDB-ID: #VU78575
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-34967
CWE-ID:
CWE-843 - Type confusion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error when parsing Spotlight mdssvc RPC packets. A remote attacker can send specially crafted data to the server, trigger a type confusion error and crash the server.
Install update from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Information disclosure
EUVDB-ID: #VU78576
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-34968
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can send a specially crafted RPC request to the server and obtain real server-side share path.
MitigationInstall update from vendor's website.

3) Security features bypass
EUVDB-ID: #VU78573
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-3347
CWE-ID:
CWE-254 - Security Features
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to SMB2 packet signing feature is not enforced if the server is configured with the "server signing = required" option or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. A remote attacker can intercept and manipulate data.

4) Infinite loop
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".
