CVSS: 7.5EPSS: 1%CPEs: 18EXPL: 2CVE-2019-5010 – python: NULL pointer dereference using a specially crafted X509 certificate
https://notcve.org/view.php?id=CVE-2019-5010
An exploitable denial-of-service vulnerability exists in the X509 certificate parser of Python.org Python 2.7.11 / 3.6.6. A specially crafted X509 certificate can cause a NULL pointer dereference, resulting in a denial of service. An attacker can initiate or accept TLS connections using crafted certificates to trigger this vulnerability. Se presenta una vulnerabilidad de denegación de servicio explotable en el analizador de certificados X509 de Python.org Python versión 2.7.11 / 3.6.6. Un certificado X509 especialmente diseñado puede causar una desreferencia del puntero NULL, resultando en una denegación de servicio. • https://github.com/JonathanWilbur/CVE-2019-5010 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://access.redhat.com/errata/RHSA-2019:3520 https://access.redhat.com/errata/RHSA-2019:3725 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html https://lists.debian.org/debian-lts-announce/2020/08/msg00034.html https://security.gentoo.org& • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 1CVE-2018-20406 – python: Integer overflow in Modules/_pickle.c allows for memory exhaustion if serializing gigabytes of data
https://notcve.org/view.php?id=CVE-2018-20406
Modules/_pickle.c in Python before 3.7.1 has an integer overflow via a large LONG_BINPUT value that is mishandled during a "resize to twice the size" attempt. This issue might cause memory exhaustion, but is only relevant if the pickle format is used for serializing tens or hundreds of gigabytes of data. This issue is fixed in: v3.4.10, v3.4.10rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.7rc1, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.7, v3.6.7rc1, v3.6.7rc2, v3.6.8, v3.6.8rc1, v3.6.9, v3.6.9rc1; v3.7.1, v3.7.1rc1, v3.7.1rc2, v3.7.2, v3.7.2rc1, v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. Modules/_pickle.c en Python, en versiones anteriores a la 3.7.1, tiene un desbordamiento de enteros mediante un valor LONG_BINPUT largo que se gestiona de manera incorrecta durante un intento de "redimensionar al tamaño doble". Este problema podría provocar el agotamiento de memoria, pero solo es relevante si el formato picke se emplea para serializar decenas o cientos de gigabytes de datos.Este problema está resuelto en las versiones: v3.4.10, v3.4.10rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.7rc1, v3.5.8, v3.5.8rc1, v3. 5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.7, v3.6.7rc1, v3.6.7rc2, v3.6.6. 8, v3.6.8rc1, v3.6.9, v3.6.9rc1; v3.7.1, v3.7.1rc1, v3.7.1rc2, v3.7.2, v3.7.2rc1, v3.7.3, v3.7.3rc1, v3.7. 4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue34656 https://github.com/python/cpython/commit/a4ae828ee416a66d8c7bf5ee71d653c2cc6a26dd https://lists.debian.org/debian-lts-announce/2019/02/msg00011.html https://lists.debian.org/debian-lts-announce/2020/07/msg00011.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/46PVWY5LFP4BRPG3BVQ5QEEFYBVEXHCK https://lists.fedorap • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2018-14647 – python: Missing salt initialization in _elementtree.c module
https://notcve.org/view.php?id=CVE-2018-14647
Python's elementtree C accelerator failed to initialise Expat's hash salt during initialization. This could make it easy to conduct denial of service attacks against Expat by constructing an XML document that would cause pathological hash collisions in Expat's internal data structures, consuming large amounts CPU and RAM. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15. El acelerador de C elementtree en Python no inicializa la sal del hash Expat durante la inicialización. Esto podría facilitar llevar a cabo ataques de denegación de servicio (DoS) contra Expat construyendo un documento XML que provocaría colisiones de hashes en las estructuras internas de datos de Expat, consumiendo grandes cantidades de CPU y RAM. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://www.securityfocus.com/bid/105396 http://www.securitytracker.com/id/1041740 https://access.redhat.com/errata/RHSA-2019:1260 https://access.redhat.com/errata/RHSA-2019:2030 https://access.redhat.com/errata/RHSA-2019:3725 https://bugs.python.org/issue34623 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14647 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.boo • CWE-335: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) CWE-665: Improper Initialization CWE-909: Missing Initialization of Resource •
