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.
Stack-based buffer overflow in the tiffsplit command in libtiff 3.8.2 and earlier might might allow attackers to execute arbitrary code via a long filename. NOTE: tiffsplit is not setuid. If there is not a common scenario under which tiffsplit is called with attacker-controlled command line arguments, then perhaps this issue should not be included in CVE.
The TIFFToRGB function in libtiff before 3.8.1 allows remote attackers to cause a denial of service (crash) via a crafted TIFF image with Yr/Yg/Yb values that exceed the YCR/YCG/YCB values, which triggers an out-of-bounds read.
