A 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 a sprintf call.
Corporate Server 3 and Corporate Desktop 3 are not affected by this vulnerability as tiff2pdf was not part of the libtiff version shipped in those products.
The updated packages have been patched to correct this issue.
