CVE-2026-85458
LowCVSS 2.1Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
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.
Risk Assessment
The vulnerability can be exploited to cause denial of service (crash) when processing specially crafted PDF files, potentially disrupting services that rely on Xpdf.
Recommendation
Update Xpdf to the latest available version that includes a fix for the divide-by-zero issue.
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-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.
- CVE-2023-3044Low
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.
