Description

According to the versions of the python-pillow packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the user-supplied stride value is trusted for buffer calculations.(CVE-2020-35653)

  • libImaging/FliDecode.c in Pillow before 6.2.2 has an FLI buffer overflow.(CVE-2020-5313)

  • In libImaging/Jpeg2KDecode.c in Pillow before 7.1.0, there are multiple out-of-bounds reads via a crafted JP2 file.(CVE-2020-10994)

  • In libImaging/SgiRleDecode.c in Pillow through 7.0.0, a number of out-of-bounds reads exist in the parsing of SGI image files, a different issue than CVE-2020-5311.(CVE-2020-11538)

  • There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.(CVE-2019-19911)

  • libImaging/TiffDecode.c in Pillow before 6.2.2 has a TIFF decoding integer overflow, related to realloc.(CVE-2020-5310)

  • An out-of-bounds write flaw was discovered in python-pillow in the way SGI RLE images are decoded. An application that uses python-pillow to decode untrusted images may be vulnerable to this flaw, which can allow an attacker to crash the application or potentially execute code on the system.(CVE-2020-5311)

  • libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX P mode buffer overflow.(CVE-2020-5312)

  • In Pillow before 7.1.0, there are two Buffer Overflows in libImaging/TiffDecode.c.(CVE-2020-10379)

  • An issue was discovered in Pillow before 6.2.0. When reading specially crafted invalid image files, the library can either allocate very large amounts of memory or take an extremely long period of time to process the image.(CVE-2019-16865)

  • In libImaging/PcxDecode.c in Pillow before 7.1.0, an out-of-bounds read can occur when reading PCX files where state->shuffle is instructed to read beyond state->buffer.(CVE-2020-10378)

  • Pillow before 7.1.0 has multiple out-of-bounds reads in libImaging/FliDecode.c.(CVE-2020-10177)
