HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service. With fix, header parsing now correctly allocates only the memory required to hold parsed headers.
A flaw was found in Golang Go, where it is vulnerable to a denial of service caused by memory exhaustion in the common function in HTTP and MIME header parsing. By sending a specially crafted request, a remote attacker can cause a denial of service.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-400: Uncontrolled Resource Consumption vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Red Hat restricts access to all platform information by default, granting access only after successful hard token-based multi-factor authentication (MFA) and enforcing least privilege to ensure only authorized roles can execute or modify code. The environment employs malicious code protections, including IDS/IPS and antimalware tools to detect threats and monitor resource usage, helping prevent uncontrolled consumption that could lead to system failure. Additional safeguards, such as web application firewalls and load-balancing strategies, protect against resource exhaustion and performance degradation. Event logs are centrally collected, correlated, and analyzed to support monitoring, alerting, and retention, aiding in the detection of abnormal behavior and potential denial-of-service (DoS) conditions. Static code analysis and peer reviews enforce strong input validation and error handling, reducing the likelihood of input-based DoS attacks.
