Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Resource exhaustion
EUVDB-ID: #VU89218
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-2024-29857
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 library does not properly control consumption of internal resources when importing an EC certificate with specially crafted F2m parameters. A remote attacker can pass a specially crafted certificate to the application to trigger resource exhaustion and perform a denial of service (DoS) attack.
MitigationInstall updates from vendor's website.

3) Infinite loop
EUVDB-ID: #VU89220
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-2024-30172
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop in the Ed25519 verification code. A remote attacker can pass a specially signature and public key to the application, consume all available system resources and cause denial of service conditions.

4) Insufficient verification of data authenticity
EUVDB-ID: #VU89221
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: N/A
CWE-ID:
CWE-345 - Insufficient Verification of Data Authenticity
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to hostname verification is performed against a DNS-resolved IP address when endpoint identification is enabled in the BCJSSE and an SSL socket is not created with an explicit hostname. A remote attacker can bypass implemented security restrictions.
