SumatraPDF Heap Buffer Overflow DoS

The vulnerability of the MobiDoc::ParseHeader function in the src/MobiDoc.cpp file of the PDF, EPUB, MOBI, FB2, CHM, XPS, and DjVu viewing software SumatraPDF lies in the reading of data beyond the allowed range of memory. Exploiting this vulnerability can allow an attacker to cause a service...

CVE-2026-26054

SumatraPDF is a multi-format reader for Windows. Prior to 3.6, the MobiDoc::ParseHeader function in src/MobiDoc.cpp validates a record using kMobiHeaderMinLen but DecodeMobiDocHeader constructs a decoder sized for kMobiHeaderLen without receiving the actual remaining buffer length. A malformed MO...
