CVE-2025-32365

Application crash via misplaced bitmap validity check

Published Apr 5, 2025 · Updated Nov 3, 2025

Out-of-bounds read in Poppler before 25.04.0 allows attackers to crash PDF-processing applications with a crafted PDF file. JBIG2Bitmap::combine in JBIG2Stream.cc dereferences the destination bitmap without first checking whether its backing allocation succeeded; the check existed only at one caller. Exploitation requires an affected application to process the crafted file, and the confirmed consequence is an application crash.
