Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Inadequate encryption strength
EUVDB-ID: #VU84537
Risk: Low
CVSSv4.0: 2.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2023-48795
CWE-ID:
CWE-326 - Inadequate Encryption Strength
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.

2) NULL pointer dereference
EUVDB-ID: #VU83930
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-2023-49083
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 when calling the load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() functions. A remote attacker can pass specially crafted PKCS7 blob/certificate certificate to the application and perform a denial of service (DoS) attack.
