| Doc Text: |
A flaw was found in Nokogiri, an XML and HTML library for Ruby. This use-after-free vulnerability occurs when replacing the value of an XML attribute. If a Ruby wrapper already points to the attribute's child node, the underlying native child node can be freed while the wrapper remains accessible. A subsequent attempt to use the freed memory or a Ruby garbage collection operation could dereference an invalid pointer, leading to an invalid read and potentially causing a segmentation fault, resulting in a Denial of Service (DoS).
