CVSS: 6.5EPSS: 1%CPEs: 21EXPL: 0CVE-2020-8927 – Buffer overflow in Brotli library
https://notcve.org/view.php?id=CVE-2020-8927
A buffer overflow exists in the Brotli library versions prior to 1.0.8 where an attacker controlling the input length of a "one-shot" decompression request to a script can trigger a crash, which happens when copying over chunks of data larger than 2 GiB. It is recommended to update your Brotli library to 1.0.8 or later. If one cannot update, we recommend to use the "streaming" API as opposed to the "one-shot" API, and impose chunk size limits. Se presenta un desbordamiento del búfer en la biblioteca Brotli versiones anteriores a 1.0.8, donde un atacante que controla la longitud de entrada de una petición de descompresión "one-shot" en un script puede desencadenar un bloqueo, que ocurre cuando se copian fragmentos de datos de más de 2 GiB . Se recomienda actualizar su biblioteca de Brotli a la versión 1.0.8 o posterior. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00108.html https://github.com/google/brotli/releases/tag/v1.0.9 https://lists.debian.org/debian-lts-announce/2020/12/msg00003.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/356JOYTWW4BWSZ42SEFLV7NYHL3S3AEH https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TOGTZ2ZWDH662ZNFFSZVL3M5AJXV6JF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-130: Improper Handling of Length Parameter Inconsistency •
CVSS: 7.5EPSS: 0%CPEs: 132EXPL: 0CVE-2020-1108 – dotnet: Denial of service via untrusted input
https://notcve.org/view.php?id=CVE-2020-1108
A denial of service vulnerability exists when .NET Core or .NET Framework improperly handles web requests, aka '.NET Core & .NET Framework Denial of Service Vulnerability'. Se presenta una vulnerabilidad denegación de servicio cuando .NET Core o .NET Framework manejan inapropiadamente las peticiones web, también se conoce como ".NET Core & .NET Framework Denial of Service Vulnerability" An integer overflow condition was found in dotnet and dotnet3.1's BinaryReader Read7BitEncodedInt() method. This method is used by BinaryReader's ReadString() method, and given a certain input, and cause a denial of service to dotnet applications using BinaryReader. The exploitation of this flaw depends on the application but does not inherently require the attacker to be authenticated or have any specific privileges. An attacker could exploit this flaw remotely via the internet by sending crafted data to a dotnet application that is passed into Read7BitEncodedInt(), resulting in a denial of service when the output is used by ReadString(). • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-1108 https://access.redhat.com/security/cve/CVE-2020-1108 https://bugzilla.redhat.com/show_bug.cgi?id=1827643 • CWE-190: Integer Overflow or Wraparound •
