{"id":"GHSA-rcrx-fpjp-mfrw","summary":"Unchecked Return Value to NULL Pointer Dereference in PDFDocumentHandler.cpp","details":"### Impact\nThe 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.\n\n### Patches\nIt has been patched in 2.6.0 for muhammara and not at all for hummus\n\n### Workarounds\nDo not process files from untrusted sources\n\n### References\nPR: https://github.com/julianhille/MuhammaraJS/pull/194\nIssue: https://github.com/julianhille/MuhammaraJS/issues/191\nIssue in hummus: https://github.com/galkahana/HummusJS/issues/293\n\n### Outline differences to https://nvd.nist.gov/vuln/detail/CVE-2022-25892\n\nThe difference is one is in [src/deps/PDFWriter/PDFParser.cpp](https://github.com/julianhille/MuhammaraJS/commit/1890fb555eaf171db79b73fdc3ea543bbd63c002#diff-09ac2c64aeab42b14b2ae7b11a5648314286986f8c8444a5b3739ba7203b1e9b) and the other is [PDFDocumentHandler.cpp](https://github.com/julianhille/MuhammaraJS/pull/194/files#diff-38d338ea4c047fd7dd9a05b5ffe7c964f0fa7e79aff4c307ccee7596457b1ef2) both is a null pointer but for different cases\nThese 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.
