Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Insufficient Entropy
EUVDB-ID: #VU71686
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-4238
CWE-ID:
CWE-331 - Insufficient Entropy
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient entropy when generating alphanumeric strings within RandomAlphaNumeric and CryptoRandomAlphaNumeric functions, which always return strings containing at least one digit from 0 to 9. A remote attacker can launch brute-force attacks and gain access to sensitive information.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Resource exhaustion
EUVDB-ID: #VU72314
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-2022-3064
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 application does not properly control consumption of internal resources when parsing large YAML documents. A remote attacker can consume excessive amounts of CPU or memory and perform a denial of service (DoS) attack.

3) Allocation of Resources Without Limits or Throttling
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.

Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
4) Out-of-bounds read
EUVDB-ID: #VU70471
Risk: Medium
CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4337
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition when parsing Auto Attach TLV. A remote attacker can send specially crafted LLDP messages to the affected system, trigger an out-of-bounds read error and read contents of memory on the system of perform a denial of service (DoS) attack.

5) Integer underflow
EUVDB-ID: #VU70459
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-4338
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer underflow when parsing Auto Attach TLV. A remote attacker can send specially crafted LLDP messages to the affected system, 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.
Note, by default interfaces are not configured to process LLDP messages.
