The filter constructors duplicate the value with pestrdup(), which stops at the first NUL byte, while keeping the original length. When the filter later emits a line break it copies the recorded length out of the truncated allocation, reading past its end and placing adjacent heap bytes into the filter output.","categories":["Runtimes & languages"],"product":"PHP","vendor":"PHP Group","ecosystem":null,"affected_ranges":[{"source":"CVE
