# Stack overflow on deeply nested LaTeX input Advisory record · `RUSTSEC-2026-0311` - **Identifiers:** `RUSTSEC-2026-0311` - **State:** Confirmed - **Severity:** No CVSS score - **Critical:** No - **Published:** 27 Sept 2026 - **Updated:** 28 Sept 2026 - **Reviewed by a person:** No Published by OSV at 27 Sept 2026, 12:00 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `latex-rust` (crates.io): affected `>=0.0.0-0, <1.0.5`; fixed in `1.0.5` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Versions of latex-rust before 1.0.5 recurse once per level of nesting in the parser and layout engine, with no limit. An attacker who can supply LaTeX input to a program that renders it can crash the process with a short string, such as a few thousand nested braces or fractions, because the stack overflow aborts rather than panics. Upgrade to latex-rust 1.0.5, which caps nesting at 32 levels and returns an error for deeper input; note that 1.0.5 also includes rendering changes from 2.0.0, so output may differ.

Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation No source has published a CVSS score for this record yet. - **CISA KEV:** Not listed. - **EPSS:** No score. ## Timeline - 31 Oct 2026, 14:24 UTC: First seen by agentprime - 31 Oct 2026, 14:24 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/RUSTSEC-2026-0311) ## Sources - [OSV: RUSTSEC-2026-0311](https://osv.dev/vulnerability/RUSTSEC-2026-0311) - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
