AI Analysis
Technical Summary
CVE-2024-45338 is a vulnerability in the golang.org/x/net/html package used by Red Hat OpenShift Container Platform. The flaw allows an attacker to craft input that causes the HTML parsing functions to process data non-linearly relative to input length, resulting in significant delays and excessive resource consumption (CPU and memory). This can lead to denial of service by exhausting system resources. Red Hat has released OpenShift Container Platform 4.12.80 containing updated container images and packages that fix this vulnerability. The advisory also addresses other vulnerabilities in golang-jwt/jwt and github.com/golang/glog. The vulnerability is rated as Important by Red Hat with a CVSS v3 base score of 7.5 (availability impact high, no confidentiality or integrity impact).
Potential Impact
An attacker can cause denial of service by sending specially crafted input that triggers non-linear parsing in the vulnerable HTML parsing library, leading to resource exhaustion (CPU and memory). This affects availability of the affected OpenShift Container Platform deployments. There is no impact on confidentiality or integrity. No known exploits in the wild have been reported.
Mitigation Recommendations
A fix is available in Red Hat OpenShift Container Platform version 4.12.80. Users should upgrade to this version using the OpenShift CLI or web console as per Red Hat's documented upgrade instructions. The vendor manages remediation for this on-premise/private cloud platform via updated container images and RPM packages. No additional mitigations are specified beyond applying the official update.
