emlparser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information. Prior to 3.0.2, emlparser.routing.noparenthesis in emlparser/routing.py removes parenthesized CFWS comments from Received: headers with a regex-based...

GHSA-G7GC-GMGP-WGQG eml_parser vulnerable to DoS via deeply nested parens in Received headers

Summary emlparser strips parenthesised CFWS comments from Received: headers using a regex-based fix-point loop. The loop has quadratic time complexity in the number of nested parens. A single Received: header containing 5,000 nested parens causes 1.3 seconds of CPU saturation per parsed message;...
