Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-45288)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.2) Out-of-bounds write (CVE-ID: CVE-2024-26586)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the mlxsw_sp_acl_tcam_init() function in drivers/net/ethernet/mellanox/mlxsw/spectrum_acl_tcam.c. A local user can trigger stack corruption and crash the kernel.
3) Error handling (CVE-ID: CVE-2024-26584)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error when handling backlogging of crypto requests in net/tls/tls_sw.c. A remote attacker can send specially crafted traffic to the system and perform a denial of service attack.
4) Use-after-free (CVE-ID: CVE-2024-26582)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error in net/tls/tls_sw.c during partial reads and async decrypt. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.
5) Missing authorization (CVE-ID: CVE-2024-1488)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to missing authorization in the unbound.service that listens on localhost on port 8953. A local user can send a specially crafted request and alter the server configuration.
6) Resource exhaustion (CVE-ID: CVE-2023-50868)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when processing DNSSEC related records. A remote attacker can trigger resource exhaustion by forcing the DNS server to query a specially crafted DNSSEC zone and perform a denial of service (DoS) attack.
7) Resource exhaustion (CVE-ID: CVE-2023-50387)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation when processing DNSSEC related records. A remote attacker can trigger resource exhaustion by forcing the DNS server to query a specially crafted DNSSEC zone and perform a denial of service (DoS) attack.
8) Resource exhaustion (CVE-ID: CVE-2023-6516)
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 processing specific recursive patterns. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack against the DNS resolver.
9) Resource exhaustion (CVE-ID: CVE-2023-49568)
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 handling responses from a Git server. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
10) Observable discrepancy (CVE-ID: CVE-2023-6240)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to a timing discrepancy when handling RSA based TLS key exchanges. A remote attacker can perform a Marvin attack and gain access to sensitive information.11) Reachable Assertion (CVE-ID: CVE-2023-5679)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion caused by a bad interaction between DNS64 and serve-stale. A remote attacker can query a DNS64-enabled resolver for domain names triggering serve-stale.
12) Reachable Assertion (CVE-ID: CVE-2023-5517)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a reachable assertion when querying RFC 1918 reverse zones. A remote attacker can send a specially crafted DNS query and perform a denial of service attack.
13) Resource exhaustion (CVE-ID: CVE-2023-4408)
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 DNS messages. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
14) Resource exhaustion (CVE-ID: CVE-2023-47108)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to grpc Unary Server Interceptor does not properly control consumption of internal resources when processing multiple requests. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
15) Information disclosure (CVE-ID: CVE-2024-1139)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to an error in the cluster monitoring operator. A remote user who has basic login credentials can check the pod manifest to discover a repository pull secret.
