CVE-2022-25892Public exploitNetwork attack vector

Node.js process crash via unchecked parser return

Published Nov 1, 2022 · Updated May 6, 2025

NULL pointer dereference in MuhammaraJS before 2.6.1 and 3.0.0 through 3.1.0 and HummusJS before 1.0.111 allows attackers to crash Node.js. PDFParser::ParseLastXrefPosition dereferences the object returned by ParseNewObject without checking whether an abruptly ended PDF produced a null result. Processing a crafted PDF whose header is followed directly by EOF causes an uncatchable SIGSEGV that terminates the hosting process; no data disclosure or modification is reported.
