CVE-2019-9517 – Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9517
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. Algunas implementaciones HTTP / 2 son vulnerables al almacenamiento en búfer de datos interal sin restricciones, lo que puede conducir a una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://www.openwall.com/lists/oss-security/2019/08/15/7 https://access.redhat.com/errata/RHSA-2019:2893 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2946 https:/ • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-9511 – Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9511
Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a la manipulación del tamaño de la ventana y la manipulación de priorización de flujo, lo que puede conducir a una denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00014.html https://access.redhat.com/errata/RHSA-2019:2692 https:/ • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-9514 – Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9514
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio. El atacante abre una serie de secuencias y envía una solicitud no válida sobre cada secuencia que debería solicitar una secuencia de tramas RST_STREAM del par. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

An issue was discovered in PDFResurrect before 0.18. pdf_load_pages_kids in pdf.c doesn't validate a certain size value, which leads to a malloc failure and out-of-bounds write. Se detectó un problema en PDFResurrect anterior a versión 0.18. La función pdf_load_pages_kids en el archivo pdf.c no comprueba un cierto valor de tamaño, lo que conlleva a un error de malloc y a una escritura fuera de límites. • https://github.com/enferex/pdfresurrect/commit/0c4120fffa3dffe97b95c486a120eded82afe8a6 https://github.com/enferex/pdfresurrect/compare/v0.17...v0.18 https://lists.debian.org/debian-lts-announce/2020/12/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4DBYXYU2VSDJ3NAL54IW2KYD3TZSR33M https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LXN6W5QTNQJ2LFDCQWKYSMMZ3NPUWP3U https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedorap • CWE-787: Out-of-bounds Write •
CVE-2019-14745
https://notcve.org/view.php?id=CVE-2019-14745
In radare2 before 3.7.0, a command injection vulnerability exists in bin_symbols() in libr/core/cbin.c. By using a crafted executable file, it's possible to execute arbitrary shell commands with the permissions of the victim. This vulnerability is due to improper handling of symbol names embedded in executables. En radare2 anterior a la versión 3.7.0, se presenta una vulnerabilidad de inyección de comandos en la función bin_symbols() en el archivo libr/core/cbin.c. Mediante el uso de un archivo ejecutable diseñado, es posible ejecutar comandos de shell arbitrarios con los permisos de la víctima. • https://github.com/xooxo/CVE-2019-14745 https://bananamafia.dev/post/r2-pwndebian https://github.com/radare/radare2/pull/14690 https://github.com/radare/radare2/releases/tag/3.7.0 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ETWG4VKHWL5F74L3QBBKSCOXHSRNSRRT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MGA2PVBFA6VPWWLMBGWVBESHAJBQ7OXJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/messag • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
