Summary
Xpdf has a vulnerability related to excessively large PDF page sizes, which can lead to a divide-by-zero error in the text extraction code. This issue was discovered during fuzz testing and is unlikely to occur in normal PDF files.
Risk Assessment
Organizations may face application crashes or unexpected behavior when processing atypical PDF files, potentially leading to data loss or service interruptions.
Recommendation
It is recommended to monitor and restrict the processing of PDF files with unusual page sizes and to update Xpdf to the latest version to minimize risk.
Other vulnerabilities in Xpdf
See all- CVE-2022-24106Low
In Xpdf prior to 4.04, the DCT (JPEG) decoder incorrectly allowed the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc. The flaw may be triggered when processing crafted PDF files.
- CVE-2026-116671Low
Infinite loop in Xpdf 4.06 and earlier, due to incorrect validation of progression order field in JPEG 2000 image.
- CVE-2026-85458Low
Xpdf 4.06 and earlier versions contain a divide-by-zero vulnerability when a glyph in a Type 3 font has a zero height. This can lead to program crashes or unexpected behavior.
- CVE-2025-11896Low
In Xpdf 4.05 (and earlier), a PDF object loop in a CMap, via the "UseCMap" entry, leads to infinite recursion and a stack overflow. This may cause an application crash when processing a malicious PDF file.
- CVE-2023-3436Low
Xpdf version 4.04 can deadlock when processing a PDF object stream whose 'Length' field is in another object stream.
Original NVD description (English source)
An excessively large PDF page size (found in fuzz testing, unlikely in normal PDF files) can result in a divide-by-zero in Xpdf's text extraction code. This is related to CVE-2022-30524, but the problem here is caused by a very large page size, rather than by a very large character coordinate.
