UBUNTU-CVE-2026-59936
A vulnerability in the pypdf Python library prior to version 6.14.1 allows an attacker to craft a PDF with a page content stream containing a not terminated inline image. This causes an infinite loop during inline image end marker detection, such as when extracting page text. The issue is fixed in version 6.14.1.
AI Analysis
Technical Summary
The pypdf library versions prior to 6.14.1 contain a vulnerability where a crafted PDF with an unterminated inline image in the page content stream can cause an infinite loop during the detection of the inline image end marker. This affects operations like extracting text from the page. The vulnerability is resolved in pypdf version 6.14.1.
Potential Impact
An attacker can cause a denial of service by triggering an infinite loop in the pypdf library when processing a specially crafted PDF. This can disrupt applications relying on pypdf for PDF parsing or text extraction. There is no indication of code execution or data disclosure from the provided data.
Mitigation Recommendations
Upgrade pypdf to version 6.14.1 or later, where this issue is fixed. No other mitigations are indicated or required.
