Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer overflow
EUVDB-ID: #VU77635
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-20892
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the DCERPC protocol implementation. A remote attacker can send specially crafted packets to the server, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Out-of-bounds read
EUVDB-ID: #VU77638
Risk: High
CVSSv3.1: 7.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-20895
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in DCERPC protocol implementation. A remote attacker can send specially crafted traffic to the server to trigger an out-of-bounds read error and read contents of memory on the system. The obtain information can be used to bypass authentication process and compromise the system.
