CVE-2007-6561
CWE-119Published: December 28, 2007· Updated: Jun 16, 2026
Official Description
Multiple stack-based buffer overflows in PDFLib allow user-assisted remote attackers to execute arbitrary code via a long filename argument to the PDF_load_image function that results in an overflow in the pdc_fsearch_fopen function, and possibly other vectors.
Technical Analysis
CVE-2007-6561 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2007-6561. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
