CVE-2026-107731 SumatraPDF: LIT parser range-validation flaws cause invalid-pointer reads and denial of service

SumatraPDF is a multi-format reader for Windows. In 3.7.0.22298, four independently reachable range-validation variants in src/LitDoc.cpp allow file-controlled offsets and sizes to overflow, narrow to negative values, or wrap before incomplete bounds checks. The affected calculations include...

CVE-2026-107730 SumatraPDF: Signed integer overflow in the LIT header parsing causes invalid-pointer read

SumatraPDF is a multi-format reader for Windows. In 3.7.0.22298, LitParseHeader in src/LitDoc.cpp computes the attacker-controlled hdrLen + nPieces 16 section offset using signed 32-bit arithmetic without validating the complete result. When the component values make that aggregate calculation...

CVE-2026-107730

The multi-format reader SumatraPDF (version 3.7.0.22298 ) contains a signed integer overflow vulnerability in the LitParseHeader() function located in src/LitDoc.cpp . The issue occurs because the software uses signed 32-bit arithmetic to compute the section offset (hdrLen + nPieces * 16) without...
