Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2024-28180)
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 decompressing JWE with Decrypt or DecryptMulti. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Untrusted search path (CVE-ID: CVE-2024-24787)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to usage of an untrusted search path in md/go. A remote attacker can trick the victim to build a Go module which contains CGO to trigger arbitrary code execution when using the Apple version of ld, due to usage of the -lto_library flag in a "#cgo LDFLAGS" directive.
3) Infinite loop (CVE-ID: CVE-2024-24788)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when processing DNS responses. A remote attacker can send a specially crafted DNS response to the application and cause denial of service conditions.
4) Resource exhaustion (CVE-ID: CVE-2024-27919)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient limitations in oghttp codec placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send a sequence of CONTINUATION frames without the END_HEADERS bit set causing unlimited memory consumption.5) Incorrect Check of Function Return Value (CVE-ID: CVE-2024-32475)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect check of function return value when using auto_sni with :authority header longer than 255 characters. A remote attacker can perform a denial of service (DoS) attack.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-8559)
The vulnerability allows a remote privileged user to execute arbitrary code.
The Kubernetes kube-apiserver in versions v1.6-v1.15, and versions prior to v1.16.13, v1.17.9 and v1.18.6 are vulnerable to an unvalidated redirect on proxied upgrade requests that could allow an attacker to escalate privileges from a node compromise to a full cluster compromise.
7) 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.Remediation
