Description PRE-NVD

Disclosed via oss-security. NVD scoring and full description are pending.

AnalysisAI

Denial of service in Apache Thrift through an integer overflow in the TProtocol::checkReadBytesAvailable() function affects C++ and c_glib bindings before 0.24.0. Attackers can send crafted messages to crash the service. No known active exploitation or public exploit code.

Technical ContextAI

Apache Thrift is a cross-language RPC framework. The vulnerability lies in the C++ and c_glib protocol implementations, where an integer overflow occurs when checking available read bytes (CWE-190 - Integer Overflow or Wraparound). Affected products include Apache Thrift before version 0.24.0, as identified by the vendor. No specific CPE strings were provided.

RemediationAI

Upgrade to Apache Thrift 0.24.0, which contains the fix. No workarounds are provided in the advisory. The official announcement is at https://seclists.org/oss-sec/2026/q3/268.
