CVSS: 5.5EPSS: 0%CPEs: 63EXPL: 0CVE-2020-8832 – Ubuntu 18.04 Linux kernel i915 incomplete fix for CVE-2019-14615
https://notcve.org/view.php?id=CVE-2020-8832
The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information. Se detectó que la solución para el kernel de Linux en Ubuntu versión 18.04 LTS para CVE-2019-14615 ("El kernel de Linux no borró apropiadamente las estructuras de datos en los conmutadores de contexto para determinados procesadores gráficos de Intel") estaba incompleta, lo que significa que en las versiones de kernel anteriores a 4.15.0-91.92, un atacante podría usar esta vulnerabilidad para exponer información confidencial. • https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862840 https://security.netapp.com/advisory/ntap-20200430-0004 https://usn.ubuntu.com/usn/usn-4302-1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp. Se detectó un problema en International Components for Unicode (ICU) para C/C++ versiones hasta 66.1. Se presenta un desbordamiento de enteros, conllevando a un desbordamiento de búfer en la región heap de la memoria, en la función UnicodeString::doAppend() en el archivo common/unistr.cpp. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00004.html https://access.redhat.com/errata/RHSA-2020:0738 https://bugs.chromium.org/p/chromium/issues/detail?id=1044570 https://chromereleases.googleblog.com/2020/02/stable-channel-update-for-desktop_24.html https://chromium.googlesource.com/chromium/deps/icu/+/9f4020916eb1f28f3666f018fdcbe6c9a37f0e08 https://github.com/unicode-org/icu/commit/b7d08bc04a4296982fcef8b6b8a354a9e4e7afca https://github.com/unicode-org/icu/pull/971 https://lists.debian • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
CVSS: 9.8EPSS: 0%CPEs: 11EXPL: 1CVE-2020-10108 – python-twisted: HTTP request smuggling when presented with two Content-Length headers
https://notcve.org/view.php?id=CVE-2020-10108
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. En Twisted Web versiones hasta 19.10.0, se presentó una vulnerabilidad de división de petición HTTP. Cuando se le presentan dos encabezados content-length, ignora el primer encabezado. • https://know.bishopfox.com/advisories https://know.bishopfox.com/advisories/twisted-version-19.10.0 https://lists.debian.org/debian-lts-announce/2022/02/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6ISMZFZBWW4EV6ETJGXAYIXN3AT7GBPL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YW3NIL7VXSGJND2Q4BSXM3CFTAFU6T7D https://security.gentoo.org/glsa/202007-24 https://usn.ubuntu.com/4308-1 https://usn.ubuntu.com/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

https://notcve.org/view.php?id=CVE-2020-10109
In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. En Twisted Web versiones hasta 19.10.0, se presentó una vulnerabilidad de división de petición HTTP. Cuando se presentó con un encabezado content-length y chunked encoding, el content-length tomó precedencia y el resto del cuerpo de la petición se interpretó como una petición canalizada "pipelined". A flaw was found in python-twisted-web, where it does not correctly process HTTP requests with both Content-Length and Transfer-Encoding headers. • https://know.bishopfox.com/advisories https://know.bishopfox.com/advisories/twisted-version-19.10.0 https://lists.debian.org/debian-lts-announce/2022/02/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6ISMZFZBWW4EV6ETJGXAYIXN3AT7GBPL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YW3NIL7VXSGJND2Q4BSXM3CFTAFU6T7D https://security.gentoo.org/glsa/202007-24 https://usn.ubuntu.com/4308-1 https://usn.ubuntu.com/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 1CVE-2020-7062 – Null Pointer Dereference in PHP Session Upload Progress
https://notcve.org/view.php?id=CVE-2020-7062
In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash. En PHP versiones 7.2.x por debajo de 7.2.28, versiones 7.3.x por debajo de 7.3.15 y versiones 7.4.x por debajo de 7.4.3, cuando es usada la funcionalidad de carga de archivos, si el seguimiento de progreso de carga está habilitado, pero session.upload_progress.cleanup está ajustado en 0 (deshabilitado), y la carga del archivo presenta un fallo, el procedimiento de carga intentaría limpiar los datos que no existan y encontraría una desreferencia del puntero null, lo que probablemente conllevaría a un bloqueo. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00023.html https://bugs.php.net/bug.php?id=79221 https://lists.debian.org/debian-lts-announce/2020/03/msg00034.html https://security.gentoo.org/glsa/202003-57 https://usn.ubuntu.com/4330-1 https://www.debian.org/security/2020/dsa-4717 https://www.debian.org/security/2020/dsa-4719 https://www.tenable.com/security/tns-2021-14 https://access.redhat.com/security/cve/CVE-2020-7062 https://bugzilla.redhat • CWE-476: NULL Pointer Dereference •
