Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2024-3596)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to use of a broken or risky cryptographic algorithm in RADIUS Protocol. A remote user can perform a man-in-the-middle (MitM) attack and gain access to target system.
2) Resource exhaustion (CVE-ID: CVE-2024-2511)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to unbounded memory growth when processing TLSv1.3 sessions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
Successful exploitation of the vulnerability requires that the non-default SSL_OP_NO_TICKET option is being used in TLSv1.3.
3) Memory leak (CVE-ID: CVE-2024-26458)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to memory leak in /krb5/src/lib/rpc/pmap_rmt.c. A remote attacker can perform a denial of service attack.
4) Resource exhaustion (CVE-ID: CVE-2024-45338)
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 in several Parse functions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Improper authorization (CVE-ID: CVE-2024-45337)
The vulnerability allows a remote attacker to gain unauthorized access to the application.
The vulnerability exists due to improper authorization caused by improper usage of the ServerConfig.PublicKeyCallback callback. A remote attacker can bypass authorization in certain cases and gain access to the application.
6) Insufficient technical documentation (CVE-ID: CVE-2024-51744)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due due to unclear documentation of the error behavior in "ParseWithClaims". A remote attacker can trick the victim into accepting invalid tokens, which can lead to information disclosure.
