The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Expr is an expression language and expression evaluation for Go. Prior to version 1.17.0, if the Expr     expression parser is given an unbounded input string, it will attempt to compile the entire string and     generate an Abstract Syntax Tree (AST) node for each part of the expression. In scenarios where input size     isn't limited, a malicious or inadvertent extremely large expression can consume excessive memory as the     parser builds a huge AST. This can ultimately lead to*excessive memory usage and an Out-Of-Memory (OOM)     crash of the process. This issue is relatively uncommon and will only manifest when there are no     restrictions on the input size, i.e. the expression length is allowed to grow arbitrarily large. In     typical use cases where inputs are bounded or validated, this problem would not occur. The problem has     been patched in the latest versions of the Expr library. The fix introduces compile-time limits on the     number of AST nodes and memory usage during parsing, preventing any single expression from exhausting     resources. Users should upgrade to Expr version 1.17.0 or later, as this release includes the new node     budget and memory limit safeguards. Upgrading to v1.17.0 ensures that extremely deep or large expressions     are detected and safely aborted during compilation, avoiding the OOM condition. For users who cannot     immediately upgrade, the recommended workaround is to impose an input size restriction before parsing. In     practice, this means validating or limiting the length of expression strings that your application will     accept. For example, set a maximum allowable number of characters (or nodes) for any expression and reject     or truncate inputs that exceed this limit. By ensuring no unbounded-length expression is ever fed into the     parser, one can prevent the parser from constructing a pathologically large AST and avoid potential memory     exhaustion. In short, pre-validate and cap input size as a safeguard in the absence of the patch.
