        "Description": "This update upgrades python3-module-Pillow to version 8.1.1-alt1. \nSecurity Fix(es):\n\n * BDU:2021-05182: Уязвимость компонента TiffDecode.c библиотеки для работы с изображениями Pillow, связанная с записью за границами буфера, позволяющая нарушителю вызвать отказ в обслуживании\n\n * BDU:2022-02667: Уязвимость библиотеки для работы с изображениями Pillow, вызванная переполнением буфера в динамической памяти, позволяющая нарушителю оказать воздействие на конфиденциальность и целостность защищаемой информации\n\n * CVE-2021-25289: An issue was discovered in Pillow before 8.1.1. TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. NOTE: this issue exists because of an incomplete fix for CVE-2020-35654.\n\n * CVE-2021-25290: An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an invalid size.\n\n * CVE-2021-25291: An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is an out-of-bounds read in TiffreadRGBATile via invalid tile boundaries.\n\n * CVE-2021-25292: An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS) attack via a crafted PDF file because of a catastrophic backtracking regex.\n\n * CVE-2021-25293: An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.\n\n * CVE-2021-27921: Pillow before 8.1.1 allows attackers to 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.\n\n * CVE-2021-27922: Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large.\n\n * CVE-2021-27923: Pillow before 8.1.1 allows attackers to 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.",
