Summary

Nokogiri: Possible Out-of-Bounds Read in `Nokogiri::XML::NodeSet#[]`

Details

Summary

Nokogiri::XML::NodeSet#[] (and its alias #slice) checked the requested index against the node set's bounds using a 32-bit-truncated copy of the index. A large negative index could pass the check and then be used at full width, reading outside the node set's storage. On CRuby this is an out-of-bounds read that typically crashes the process; on JRuby it is not memory-unsafe but returns an incorrect node.

Nokogiri 1.19.4 performs the bounds check against the full-width index.

Severity

The Nokogiri maintainers have evaluated this as medium severity.

Exploitation requires an application to pass an attacker-controlled integer to NodeSet#[]. The primary impact is a controlled crash (denial of service), with potential for memory disclosure on CRuby.

On JRuby, Nokogiri is not affected by this vulnerability.

Mitigation

Upgrade to Nokogiri 1.19.4 or later.

As a workaround, applications that index a NodeSet with externally-supplied integers can validate the index against node_set.length before use, or avoid passing untrusted values as an index.
