CVSS: 9.8EPSS: 0%CPEs: 5EXPL: 0CVE-2021-34552 – python-pillow: Buffer overflow in image convert function
https://notcve.org/view.php?id=CVE-2021-34552
Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c. Pillow versiones hasta 8.2.0 y PIL (también se conoce como Python Imaging Library) versiones hasta 1.1.7, permiten a un atacante pasar parámetros controlados directamente a una función de conversión para desencadenar un desbordamiento de búfer en el archivo Convert.c 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. • https://lists.debian.org/debian-lts-announce/2021/07/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7V6LCG525ARIX6LX5QRYNAWVDD2MD2SV https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VUGBBT63VL7G4JNOEIPDJIOC34ZFBKNJ https://pillow.readthedocs.io/en/stable/releasenotes/8.3.0.html#buffer-overflow https://pillow.readthedocs.io/en/stable/releasenotes/index.html https://security.gentoo.org/glsa/202211-10 https://access.redha • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2021-28678 – python-pillow: Excessive looping in BLP image reader
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 •

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.
