https://notcve.org/view.php?id=CVE-2021-28678
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 •
