Summary: Unchecked Return Value to NULL Pointer Dereference in PDFDocumentHandler.cpp
Details: ### 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](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 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.
