An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data. Se ha detectado un problema en Pillow versiones anteriores a 8.2.0,. En el caso de los datos BLP, la función BlpImagePlugin no comprobaba apropiadamente que las lecturas (después de saltar a los offsets de los archivos) devolvían datos. • https://github.com/python-pillow/Pillow/pull/5377 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQHA5HAIBOYI3R6HDWCLAGFTIQP767FL https://pillow.readthedocs.io/en/stable/releasenotes/8.2.0.html#cve-2021-28678-fix-blp-dos https://security.gentoo.org/glsa/202107-33 https://access.redhat.com/security/cve/CVE-2021-28678 https://bugzilla.redhat.com/show_bug.cgi?id=1958263 • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •

An issue was discovered in Pillow before 8.2.0. There is an out-of-bounds read in J2kDecode, in j2ku_gray_i. Se ha detectado un problema en Pillow versiones anteriores a 8.2.0,. Se presenta una lectura fuera de límites en J2kDecode, en la función j2ku_gray_i There is an out-of-bounds read in J2kDecode in j2ku_gray_i. For J2k images with multiple bands, it’s legal to have different widths for each band, e.g. 1 byte for L, 4 bytes for A. • https://github.com/python-pillow/Pillow/pull/5377#issuecomment-833821470 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQHA5HAIBOYI3R6HDWCLAGFTIQP767FL https://pillow.readthedocs.io/en/stable/releasenotes/8.2.0.html#cve-2021-25287-cve-2021-25288-fix-oob-read-in-jpeg2kdecode https://security.gentoo.org/glsa/202107-33 https://access.redhat.com/security/cve/CVE-2021-25288 https://bugzilla.redhat.com/show_bug.cgi?id=1958231 • CWE-125: Out-of-bounds Read •

An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the number of input layers relative to the size of the data block. This could lead to a DoS on Image.open prior to Image.load. Se ha detectado un problema en Pillow versiones anteriores a 8.2.0, PSDImagePlugin.PsdImageFile carecía de una comprobación de saneamiento sobre el número de capas de entrada en relación con el tamaño del bloque de datos. Esto podría conllevar a un DoS en Image.open anterior a Image.load A flaw was found in python-pillow. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MQHA5HAIBOYI3R6HDWCLAGFTIQP767FL https://pillow.readthedocs.io/en/stable/releasenotes/8.2.0.html#cve-2021-28675-fix-dos-in-psdimageplugin https://security.gentoo.org/glsa/202107-33 https://access.redhat.com/security/cve/CVE-2021-28675 https://bugzilla.redhat.com/show_bug.cgi?id=1958240 • CWE-20: Improper Input Validation CWE-252: Unchecked Return Value •

An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the block advance was non-zero, potentially leading to an infinite loop on load. Se detectó un problema en Pillow versiones anteriores a 8.2.0,. En el caso de los datos FLI, la función FliDecode no comprobaba correctamente que el avance del bloque fuera distinto de cero, lo que podía conllevar un bucle infinito en la carga A flaw was found in python-pillow.
