TIFF library (libtiff) before 3.8.2 allows context-dependent attackers to pass numeric range checks and possibly execute code, and trigger assert errors, via large offset values in a TIFF directory that lead to an integer overflow and other unspecified vectors involving "unchecked arithmetic operations".
Unspecified vulnerability in the custom tag support for the TIFF library (libtiff) before 3.8.2 allows remote attackers to cause a denial of service (instability or crash) and execute arbitrary code via unknown vectors.
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.
