CyberRota Analysis
AI-GeneratedThe RaTeX math rendering engine prior to version 0.1.11 is vulnerable to a denial-of-service attack due to a panic triggered by specific non-ASCII input in the `\verb` command, which causes the entire process to abort. This vulnerability can disrupt services that render untrusted LaTeX, making it critical for developers and system administrators using RaTeX to prioritize upgrading to version 0.1.11 or later to mitigate the risk.

Original NVD Description
RaTeX is a KaTeX-compatible math rendering engine written in Rust. Prior to version 0.1.11, the public parser entrypoint `ratex_parser::parse(&str)` panics on the 9-byte input `\verbéxé` (i.e. `\verb` followed by the non-ASCII delimiter `é`). When handling a `\verb` command, the parser slices the verbatim argument with byte indices (`arg[1..arg.len() - 1]`); if the delimiter character is multibyte UTF-8, index `1` lands inside that character and Rust panics with *“byte index 1 is not a char boundary”*. Because RaTeX’s release profile sets `panic = "abort"` (`Cargo.toml:48`), the panic aborts the entire process — not just the current request/thread — making this a hard denial of service for any service that renders untrusted LaTeX. Version 0.1.11 fixes the issue.
