• npm muhammara: < 2.6.0 → fixed in 2.6.0 • npm hummus: < 1.0.111 → fixed in 1.0.111

Impact The package muhammara before 2.6.0; all versions of package hummus are vulnerable to Denial of Service (DoS) when supplied with a maliciously crafted PDF file to be appended to another. Patches It has been patched in 2.6.0 for muhammara and not at all for hummus Workarounds Do not process files from untrusted sources References PR: https://github.com/julianhille/MuhammaraJS/pull/194 Issue: https://github.com/julianhille/MuhammaraJS/issues/191 Issue in hummus: https://github.com/galkahana/HummusJS/issues/293 Outline differences to https://nvd.nist.gov/vuln/detail/CVE-2022-25892 The difference is one is in src/deps/PDFWriter/PDFParser.cpp and the other is PDFDocumentHandler.cpp both is a null pointer but for different cases These are totally diffent issues, one is in reading a pdf the other is in appendending a maliciously crafted one. The function calls are different the versions in which they are solved are diffent.
