ModSecurity is announcing the release of versions 2.9.5 and 3.0.6. Each of these releases contains only one notable change when compared with their respective predecessors. A researcher identified a scenario where JSON-formatted HTTP request bodies with very large parsing depth could be used to enable a DoS attack. Both the v2 and v3 branches have been updated to address the issue by providing a configurable limit on the maximum parsing depth. The change entries in the releases are as follows: v3.0.6: Security issue - Support configurable limit on depth of JSON parsing (possible DoS issue) [@theMiddleBlue, @martinhsv] v2.9.5: Security issue - Support configurable limit on depth of JSON parsing (possible DoS issue) [@theMiddleBlue, @airween, @dune73, @martinhsv] A blog post with additional detail is expected to be posted at https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/ within a day. A new issue is also planned for https://github.com/SpiderLabs/ModSecurity/issues to provide a summary. Links to the github releases, which includes the change list and source (and related hashes and signatures) are: https://github.com/SpiderLabs/ModSecurity/releases/tag/v3.0.6 https://github.com/SpiderLabs/ModSecurity/releases/tag/v2.9.5 Releases of ModSecurity 2.9.x are normally accompanied by IIS assets, however these are not yet available and are expected to be published separately in a few days.
