Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
EUVDB-ID: #VU70334
Risk: Medium
CVSSv3.1: 4.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-41717
CWE-ID:
CWE-770 - Allocation of Resources Without Limits or Throttling
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
MitigationInstall updates from vendor's repository.

EUVDB-ID: #VU82064
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-39325
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.

EUVDB-ID: #VU84537
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-48795
CWE-ID:
CWE-326 - Inadequate Encryption Strength
Exploit availability: No
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.
