Description
This security bulletin contains information about 6 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-33202)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: 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
The 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 OpenSSL PEM encoded streams containing X.509 certificates. A remote attacker can send ASN.1 data through the PEMParser to trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2025-8916)
CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to improper resource allocation. A remote attacker can library to consume excessive resources and perform a denial of service attack.
3) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2026-5588)
CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to bypass signature verification.
The vulnerability exists due to use of a broken or risky cryptographic algorithm in the PKIX draft CompositeVerifier when processing composite signatures. A remote attacker can provide an empty signature sequence to bypass signature verification.
4) Incorrect calculation (CVE-ID: CVE-2025-14813)
CWE-ID: CWE-682 - Incorrect Calculation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause cryptographic operations to fail.
The vulnerability exists due to improper implementation in G3413CTRBlockCipher when encrypting or decrypting more than 255 blocks. A remote attacker can supply data that exceeds this limit to cause cryptographic operations to fail.
The issue affects the GOST-R-3413-2015 CTR mode implementation because it uses a single-byte counter instead of a counter size aligned with the algorithm definition.
5) Covert Timing Channel (CVE-ID: CVE-2026-5598)
CWE-ID: CWE-385 - Covert Timing Channel
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to disclose sensitive information.
The vulnerability exists due to a covert timing channel in FrodoEngine.java in the BC-JAVA core modules when performing cryptographic operations. A remote attacker can measure timing differences to disclose sensitive information.
6) LDAP injection (CVE-ID: CVE-2026-0636)
CWE-ID: CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to manipulate LDAP queries.
The vulnerability exists due to improper neutralization of special elements used in an LDAP query in LDAPStoreHelper when processing user-supplied input for LDAP queries. A remote attacker can supply crafted input to manipulate LDAP queries.
This issue is associated with the prov modules.
