• tif_fax3.c: Error out for CCITT fax encoding if SamplesPerPixel is not equal 1 and PlanarConfiguration = Contiguous (fixes issue #26)
• tif_fax3.c: error out after a number of times end-of-line or unexpected bad code words have been reached. (fixes issue #670)
• Fix memory leak in TIFFSetupStrips() (fixes issue #665)
• tif_zip.c: Provide zlib allocation functions. Otherwise for zlib built with -DZ_SOLO inflating will fail.
• Fix memory leak in _TIFFSetDefaultCompressionState. (fixes issue #676)
• tif_predict.c: Don’t overwrite input buffer of TIFFWriteScanline() if "prediction" is enabled. Use extra working buffer in PredictorEncodeRow(). (fixes issue #5)
• tif_getimage.c: update some integer overflow checks (fixes issue #79)
• tif_getimage.c: Fix buffer underflow crash for less raster rows at TIFFReadRGBAImageOriented() (fixes issue #704, bsc#1250413, CVE-2025-9900)
• TIFFReadRGBAImage(): several fixes to avoid buffer overflows.
• Correct passing arguments to TIFFCvtIEEEFloatToNative() and TIFFCvtIEEEDoubleToNative() if HAVE_IEEEFP is not defined. (fixes issue #699)
• LZWDecode(): avoid nullptr dereference when trying to read again after EOI marker has been found with remaining output bytes (fixes issue #698)
• TIFFSetSubDirectory(): check _TIFFCheckDirNumberAndOffset() return.
• TIFFUnlinkDirectory() and TIFFWriteDirectorySec(): clear tif_rawcp when clearing tif_rawdata (fixes issue #711)
• JPEGEncodeRaw(): error out if a previous scanline failed to be written, to avoid out-of-bounds access (fixes issue #714)
• tif_jpeg: Fix bug…

It was discovered that LibTIFF incorrectly handled certain memory operations when using tiffmedian tool. An attacker could trick a user into processing a specially crafted tiff image file and potentially use this issue to cause a denial of service. (CVE-2025-8176)

It was discovered that LibTIFF did not properly perform bounds checking in certain operations when using thumbnail tool. An attacker could trick a user into processing a specially crafted tiff image file and potentially use this issue to cause a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2025-8177)

It was discovered that LibTIFF incorrectly handled certain memory
operations when using tiff2ps tool. An attacker could trick a user into processing a specially crafted tiff image file and potentially use this issue to cause a denial of service. (CVE-2025-8534)

It was discovered that LibTIFF did not properly perform bounds checking
in certain operations when using tiffcrop tool. An attacker could trick
a user into processing a specially crafted tiff image file and
potentially use this issue to cause a denial of service. (CVE-2025-8851)
