CWE

CWE ID Description
CWE-122 A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
CWE-190 The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
CWE-770 The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.

Executive Summary

This vulnerability involves three types of issues in Apache Thrift: resource exhaustion without limits, integer overflow, and heap-based buffer overflow. These flaws allow attackers to cause crashes or execute arbitrary code by exploiting improper memory handling or resource allocation.

Detection Guidance

Detection requires checking Apache Thrift versions. Run 'thrift --version' or inspect package managers like 'dpkg -l | grep thrift' or 'rpm -qa | grep thrift'. If version is before 0.25.0, the system is vulnerable.

Impact Analysis

An attacker could exploit this to crash services, execute malicious code, or gain unauthorized access to systems running vulnerable versions of Apache Thrift. This may lead to data breaches, service disruption, or further network compromise.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by enabling unauthorized access or data breaches due to heap-based buffer overflows and integer overflows. Such flaws may lead to data exposure or corruption, violating confidentiality and integrity requirements under these regulations.

Mitigation Strategies

Upgrade Apache Thrift to version 0.25.0 or later immediately. Use package managers like 'apt upgrade thrift' or 'yum update thrift'. If direct upgrade isn't possible, apply vendor patches or restrict network access to Thrift services.
