Description

A flaw was found in PHP's parsing of multipart form data contents, which affects both file and input form data. This may lead to legitimate data not being processed, violating data integrity. For example, if a multipart form data payload contains a valid prefix 'X' of the defined boundary B such that 5Kib < |X| < |B| < 8Kib, the logic responsible for parsing and storing the multipart payload fails to correctly extract the contents between two boundaries.
