Security readout for executives and security teams
Plain-English summary
A remote, unauthenticated attacker can send specially crafted requests that crash an Apache Thrift server using the c_glib bindings. The primary business impact is service interruption, not disclosed data theft or alteration. Apache Thrift releases before 0.23.0 are affected; version 0.23.0 fixes the issue.
Executive priority
Prioritize internet-facing or broadly reachable c_glib Thrift servers for prompt remediation because disruption requires no credentials or user action. Internal, tightly restricted instances still require scheduled upgrading. The evidence supports high availability risk, but not data compromise or confirmed exploitation.
Technical view
Apache Thrift c_glib bindings before 0.23.0 use mismatched memory-management routines. Crafted network input can trigger an invalid-pointer free and terminate the server. CVSS 3.1 is 7.5: network-accessible, low complexity, no privileges or user interaction, with high availability impact and no stated confidentiality or integrity impact.
Likely exposure
Exposure requires an Apache Thrift server using the c_glib language bindings on a version before 0.23.0. Risk is greatest where untrusted clients can reach its Thrift endpoint. Deployments using other bindings, version 0.23.0 or newer, or no Thrift server are not established as affected by this bundle.
Exploitation context
The supplied record is not in KEV, and the sources provided do not establish active exploitation or a public exploit. Nevertheless, the CVSS vector describes unauthenticated network reachability and low attack complexity. Successful triggering causes a fatal server crash, making repeated denial-of-service attempts plausible where the endpoint is reachable.
Researcher notes
The issue maps to CWE-762 and CWE-763, indicating deallocation with an incompatible or mismatched memory-management routine. Available evidence describes a clean but fatal invalid-pointer failure. It does not establish code execution, information disclosure, integrity impact, affected non-c_glib bindings, exploit availability, or observed attacks.
Mitigation direction
- Upgrade affected Apache Thrift c_glib deployments to version 0.23.0 or newer.
- Apply applicable downstream vendor updates where Apache Thrift is supplied as a packaged dependency.
- Restrict untrusted access to affected Thrift endpoints until upgrades are completed.
- Review Apache and downstream vendor advisories for deployment-specific instructions.
Validation and detection
- Inventory Apache Thrift versions and identify services using the c_glib bindings.
- Confirm whether affected Thrift endpoints accept connections from untrusted networks or clients.
- Verify deployed binaries and dependencies report Apache Thrift 0.23.0 or newer.
- Review service logs and crash records for fatal "free(): invalid pointer" errors.
- Confirm services remain healthy after upgrading through normal functional and availability testing.
