Executive Summary

This is a memory allocation vulnerability where Apache Thrift libraries in multiple languages (Go, Java, Rust, C++, etc.) allocate excessive memory due to unchecked size values. This can lead to denial of service or system crashes by exhausting available memory resources.

Detection Guidance

This vulnerability involves memory allocation with excessive size values in Apache Thrift. To detect it, check the version of Apache Thrift installed on your system. If it is before 0.25.0, the system is vulnerable. Use commands like 'thrift --version' or inspect package managers (e.g., 'dpkg -l | grep thrift' for Debian-based systems or 'rpm -qa | grep thrift' for RPM-based systems) to verify the installed version.

Impact Analysis

If exploited, this vulnerability could cause applications using affected Thrift versions to crash or become unresponsive due to memory exhaustion. This may disrupt services relying on Thrift for communication between systems.

Compliance Impact

The vulnerability involves memory allocation with excessive size values, which could lead to resource exhaustion or denial-of-service conditions. This may impact compliance by disrupting availability of systems handling sensitive data, potentially violating requirements for continuous access in standards like HIPAA or GDPR.

Mitigation Strategies

Upgrade Apache Thrift to version 0.25.0 or later to address the memory allocation vulnerability.
