Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of ratex-parser before 0.1.11 are affected by unbounded parser recursion. Deeply nested groups in a LaTeX input, such as nested braces or \left commands, can overflow the native stack and abort the process. An unauthenticated attacker who can submit a single crafted LaTeX string to a service using the library can crash the whole process, causing denial of service. Upgrade to ratex-parser 0.1.11 or later, which is listed as the fixed version.
