A flaw was found in python-pillow. Attackers can cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICO container, and thus an attempted memory allocation can be very large.

A flaw was found in python-pillow. Attackers can cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for a BLP container, and thus an attempted memory allocation can be very large.
libImaging/TgaRleDecode.c in Pillow 9.1.0 has a heap buffer overflow in the processing of invalid TGA image files.
PIL.ImageMath.eval in Pillow before 9.0.0 allows evaluation of arbitrary expressions, such as ones that use the Python exec method ImageMath.eval("exec(exit())").
While Pillow 9.0.0 restricted top-level builtins available to PIL.ImageMath.eval(), it did not prevent builtins available to lambda expressions. These are now also restricted in 9.0.1.
A flaw was found in python-pillow. The readline used in EPS has to deal with any combination of \r and \n as line endings. It accidentally used a quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could use this to perform a denial-of-service of Pillow in the open phase, before an image was accepted for opening.
A flaw was found in python-pillow. BlpImagePlugin did not properly check that reads after jumping to file offsets returned data. This could lead to a denial-of-service where the decoder could be run a large number of times on empty data.
pathgetbbox in path.c in Pillow before 9.0.0 has a buffer over-read during initialization of ImagePath.Path.
pathgetbbox in path.c in Pillow before 9.0.0 improperly initializes ImagePath.Path.
Pillow before 9.0.1 allows attackers to delete files because spaces in temporary pathnames are mishandled.
A flaw was found in python-pillow. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A flaw was found in python-pillow. FliDecode.c did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load. This issue dates to the PIL fork. The highest threat from this vulnerability is to system availability.
A flaw was found in python-pillow. Invalid tile boundaries could lead to an OOB Read in TiffReadRGBATile in TiffDecode.c.
A flaw was found in python-pillow. The PDF parser has a catastrophic backtracking regex that could be used as a DOS attack.
Heap-based buffer overflow in the j2kencodeentry function in Pillow 2.5.0 through 3.1.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted Jpeg2000 file.
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2kugrayi.
An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2kugrayala.
A flaw was found in python-pillow. This flaw allows an attacker to pass controlled parameters directly into a convert function, triggering a buffer overflow in the "convert()" or "ImagingConvertTransparent()" functions in Convert.c. The highest threat to this vulnerability is to system availability. In Red Hat Quay, a vulnerable version of python-pillow is shipped with quay-registry-container, however the invoice generation feature which uses python-pillow is disabled by default. Therefore impact has been rated Moderate.
The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function.
The Jpeg2KImagePlugin plugin in Pillow before 2.5.3 allows remote attackers to cause a denial of service via a crafted image.
A flaw was found in python-pillow. There is an Out of Bounds Read in SGIRleDecode.c.
Buffer overflow in the ImagingFliDecode function in libImaging/FliDecode.c in Pillow before 3.1.1 allows remote attackers to cause a denial of service (crash) via a crafted FLI file.
A flaw was found in python-pillow. PsdImagePlugin.PsdImageFile does not sanity check the number of input layers with regard to the size of the data block which could lead to a denial-of-service.
Buffer overflow in the ImagingLibTiffDecode function in libImaging/TiffDecode.c in Pillow before 3.1.1 allows remote attackers to overwrite memory via a crafted TIFF file.
A flaw was found in python-pillow. In TiffDecode.c, there is a negative-offset memcpy with an invalid size which could lead to a system crash.
A flaw was found in python-pillow. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. The previous fix for CVE-2020-35654 was insufficient due to incorrect error checking in TiffDecode.c. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Buffer overflow in the ImagingPcdDecode function in PcdDecode.c in Pillow before 3.1.1 and Python Imaging Library (PIL) 1.1.7 and earlier allows remote attackers to cause a denial of service (crash) via a crafted PhotoCD file.
PIL/IcnsImagePlugin.py in Python Imaging Library (PIL) and Pillow before 2.3.2 and 2.5.x before 2.5.2 allows remote attackers to cause a denial of service via a crafted block size.
Integer overflow in the ImagingResampleHorizontal function in libImaging/Resample.c in Pillow before 3.1.1 allows remote attackers to have unspecified impact via negative values of the new size, which triggers a heap-based buffer overflow.
Pillow before 3.3.2 allows context-dependent attackers to obtain sensitive information by using the "crafted image file" approach, related to an "Integer Overflow" issue affecting the Image.core.mapbuffer in map.c component.
