Detailsinfo

A vulnerability, which was classified as critical, was found in PDFLib 7.0.2. This affects the function pdc_fsearch_fopen. The manipulation of the argument filename with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. The summary by CVE is:

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.
