CVE-2006-2193

High
Published: Translated: NVD NIST

Summary

A buffer overflow vulnerability exists in the t2p_write_pdf_string function of tiff2pdf in libtiff versions 3.8.2 and earlier. An attacker can exploit a specially crafted TIFF file with a DocumentName tag containing UTF-8 characters, causing a crash and potentially arbitrary code execution.

Risk Assessment

The risk includes potential remote code execution on the system, which could lead to full compromise of the application processing TIFF files, affecting data confidentiality, integrity, and availability.

Recommendation

Immediately update libtiff to version 3.8.3 or later, which includes a fix for this vulnerability. As a workaround, restrict processing of TIFF files from untrusted sources.

Original NVD description (English source)

Buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier 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.
