RHSA-2025%3A3993 PUBLISHED CVSS 7.5 HIGH

A flaw was found in Expr. This vulnerability allows excessive memory usage and potential out-of-memory (OOM) crashes via unbounded input strings, where a malicious or inadvertent large expression can cause the parser to construct an extremely large Abstract Syntax Tree (AST), consuming excessive memory.
