Name of the Vulnerable Software and Affected Versions Apache Thrift versions prior to 0.25.0
Description The protocol skip routine in several Apache Thrift bindings fails to apply the recursion limit. This allows a message containing deeply nested unknown fields to exhaust the stack, potentially leading to a denial of service. This issue specifically affects the Python C++ accelerator, the PHP library and its thrift protocol extension, and the Perl, Lua, Smalltalk, and OCaml libraries.
Recommendations Upgrade to version 0.25.0.
