CVE-2023-29583
CSIRTS triage
- What
- A stack overflow exists in the parse_expr5 function in the NASM parser component.
- Who is affected
- Users processing untrusted assembly source code with Yasm 1.3.0.55.g101bc are affected, though the vulnerability is disputed as yasm is a standalone assembler not designed for untrusted input.
- Urgency
- Medium severity with disputed classification; remediation depends on your assessment of untrusted input exposure in your environment.
- Action
- Update Yasm to a version with the stack overflow fixed, or restrict input to trusted sources if untrusted assembly code is unlikely in your use case.
