cve 2026 55969

The cve 2026 55969 tag on WindowsForum.com covers discussions about CVE-2026-55969, a denial-of-service vulnerability in Apache Thrift. The tag highlights that Apache Thrift deployments using C++, C/GLib, Go, .NET Standard, Delphi, or Haxe bindings should update to version 0.24.0 to address the issue. The vulnerability allows a remote peer to bypass message-size prechecks with oversized container declarations, potentially exhausting service resources. Windows-specific details include a concern about the original fix overflowing under Microsoft's 64-bit C++ data model, which Apache corrected with fixed-width 64-bit arithmetic. Microsoft's Security Update Guide published an entry on August 11, describing the outcome as serious availability loss. The tag focuses on the technical aspects of the fix and its relevance to Windows environments.
