Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Resource management error
EUVDB-ID: #VU82894
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-5678
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

3) Resource management error
EUVDB-ID: #VU85399
Risk: Low
CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-6237
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the way the EVP_PKEY_public_check() function handles RSA public keys. A remote attacker can supply an RSA key obtained from an untrusted source and perform a denial of service (DoS) attack.
