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') •

Nextcloud Server is a Nextcloud package that handles data storage. In versions prior to 19.0.13, 20.011, and 21.0.3, there was a lack of ratelimiting on the public DAV endpoint. This may have allowed an attacker to enumerate potentially valid share tokens or credentials. The issue was fixed in versions 19.0.13, 20.0.11, and 21.0.3. There are no known workarounds. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-fjv7-283f-5m54 https://github.com/nextcloud/server/pull/27610 https://hackerone.com/reports/1192159 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-307: Improper Restriction of Excessive Authentication Attempts CWE-799: Improper Control of Interaction Frequency •

Nextcloud Server is a Nextcloud package that handles data storage. Nextcloud Server supports application specific tokens for authentication purposes. These tokens are supposed to be granted to a specific applications (e.g. DAV sync clients), and can also be configured by the user to not have any filesystem access. Due to a lacking permission check, the tokens were able to change their own permissions in versions prior to 19.0.13, 20.0.11, and 21.0.3. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-48m7-7r2r-838r https://github.com/nextcloud/server/pull/27000 https://hackerone.com/reports/1193321 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BVZS26RDME2DYTKET5AECRIZDFUGR2AZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J63NBVPR2AQCAWRNDOZSGRY5II4WS2CZ https://security.gentoo.org/glsa/202208-17 • CWE-285: Improper Authorization CWE-552: Files or Directories Accessible to External Parties •
