thrift: Apache Thrift: Denial of Service via deeply nested unknown fields
zetlyn/cve-redhat · 2026-10-02
cvss 7.5 cwe CWE-770 packages thrift-main-0.25.0-0.1.hum1 severity important source
The protocol skip routine in several Apache Thrift bindings did not apply the binding's recursion limit, so a message that nests unknown fields deeply enough can exhaust the stack. Affected: the Python C++ accelerator (the pure-Python protocols are not affected), the PHP library and its thrift_protocol extension, and the Perl, Lua, Smalltalk and OCaml libraries. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.
