osslsigncode is a tool that implements Authenticode signing and timestamping. Prior to 2.13, an integer underflow vulnerability exists in osslsigncode version 2.12 and earlier in the PE page-hash computation code pepagehashcalc. When page hash processing is performed on a PE file, the function...

CVE-2026-39855

osslsigncode prior to 2.13 contains an integer underflow in the PE page-hash calculation (pe_page_hash_calc). If SizeOfHeaders (hdrsize) > SectionAlignment (pagesize), hdrsize is subtracted from pagesize without validation, producing a large unsigned length. The code allocates a zero-filled bu...
