Security¶
CVE 2021-23437: Avoid potential ReDoS (regular expression denial of service)¶
Avoid a potential ReDoS (regular expression denial of service) in ImageColor
’s
getrgb()
by raising ValueError
if the color specifier is
too long. Present since Pillow 5.2.0.
Fix 6-byte out-of-bounds (OOB) read¶
Fix 6-byte out-of-bounds (OOB) read. The previous bounds check in FliDecode.c
incorrectly
calculated the required read buffer size when copying a chunk, potentially reading six extra
bytes off the end of the allocated buffer from the heap. Present since Pillow 7.1.0.
Other Changes¶
Python 3.10 wheels¶
Pillow now includes binary wheels for Python 3.10.
The Python 3.10 release candidate was released on 2021-08-03 with the final release due 2021-10-04 (PEP 619). The CPython core team strongly encourages maintainers of third-party Python projects to prepare for 3.10 compatibility. And as there are no ABI changes planned we are releasing wheels to help others prepare for 3.10, and ensure Pillow can be used immediately on release day of 3.10.0 final.
Fixed regressions¶
Ensure TIFF
RowsPerStrip
is multiple of 8 for JPEG compression (#5588).Updates for
ImagePalette
channel order (#5599).Hide FriBiDi shim symbols to avoid conflict with real FriBiDi library (#5651).
