pnet fixed: 0.27.2 
Upgrade pnet to 0.27.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for pnet

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-25054, inspect your project dependencies for Pnet:

inspect dependencies for pnet

Analyze the terminal output to locate any version of Pnet in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.27.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-909: Missing Initialization of Resource, where the product does not initialize a critical resource. In Pnet, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue was discovered in the pnet crate before 0.27.2 for Rust. There is a segmentation fault (upon attempted dereference of an uninitialized descriptor) because of an erroneous IcmpTransportChannelIterator compiler optimization.
