 * :cve:`CVE-2020-35654` Fix TIFF OOB Write error
 
-OOB Write in TiffDecode.c when reading corrupt YCbCr files in some LibTIFF versions
+OOB Write in ``TiffDecode.c`` when reading corrupt YCbCr files in some LibTIFF versions
 (4.1.0/Ubuntu 20.04, but not 4.0.9/Ubuntu 18.04). In some cases LibTIFF's
 interpretation of the file is different when reading in RGBA mode, leading to an Out of
-bounds write in TiffDecode.c. This potentially affects Pillow versions from 6.0.0 to
+bounds write in ``TiffDecode.c``. This potentially affects Pillow versions from 6.0.0 to
 8.0.1, depending on the version of LibTIFF. This was reported through `Tidelift`_.
