Stack-based Buffer Overflow
CVE-2006-2193
Summary
Buffer overflow in the "t2p_write_pdf_string" function in tiff2pdf in libtiff through 3.8.2 allows attackers to cause a Denial of Service (crash) and possibly execute arbitrary code via a "TIFF" file with a "DocumentName" tag that contains UTF-8 characters, which triggers the overflow when a character is sign extended to an integer that produces more digits than expected in an sprintf call.
