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 •

Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to inject code. Artifex Ghostscript en versiones anteriores a la 9.25 permitía una tabla de excepción de error que puede escribir el usuario. Esta tabla podía ser usada por los atacantes remotos capaces de proporcionar PostScript manipulados para poder sobrescribir o reemplazar manipuladores de errores para inyectar código. • http://git.ghostscript.com/?p=ghostpdl.git%3Ba=commit%3Bh=fb713b3818b52d8a6cf62c951eba2e1795ff9624 https://access.redhat.com/errata/RHSA-2018:3834 https://bugs.ghostscript.com/show_bug.cgi?id=699708 https://lists.debian.org/debian-lts-announce/2018/09/msg00038.html https://usn.ubuntu.com/3773-1 https://access.redhat.com/security/cve/CVE-2018-17183 https://bugzilla.redhat.com/show_bug.cgi?id=1632471 • CWE-460: Improper Cleanup on Thrown Exception •
CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2017-15705 – spamassassin: Certain unclosed tags in crafted emails allow for scan timeouts and result in denial of service
https://notcve.org/view.php?id=CVE-2017-15705
A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html http://www.securityfocus.com/bid/105347 https://access.redhat.com/errata/RHSA-2018:2916 https://lists.apache.org/thread.html/7f6a16bc0fd0fd5e67c7fd95bd655069a2ac7d1f88e42d3c853e601c%40%3Cannounce.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00016.html https://security.gentoo.org/glsa/201812-07 https://usn.ubuntu.com/3811-1 https://usn.ubuntu.com/3811-2 https://access.redhat.com/security/cve/CVE& • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •

Apache SpamAssassin 3.4.2 fixes a local user code injection in the meta rule syntax. Apache SpamAssassin 3.4.2 soluciona una inyección de código de usuario local en la sintaxis de reglas meta. A flaw was found in the way a local user on the SpamAssassin server could inject code in the meta rule syntax. This could cause the arbitrary code execution on the server when these rules are being processed. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00002.html https://access.redhat.com/errata/RHSA-2018:2916 https://lists.apache.org/thread.html/7f6a16bc0fd0fd5e67c7fd95bd655069a2ac7d1f88e42d3c853e601c%40%3Cannounce.apache.org%3E https://lists.debian.org/debian-lts-announce/2018/11/msg00016.html https://security.gentoo.org/glsa/201812-07 https://usn.ubuntu.com/3811-1 https://usn.ubuntu.com/3811-3 https://access.redhat.com/security/cve/CVE-2018-11781 https://bugzilla.redhat.com • CWE-94: Improper Control of Generation of Code ('Code Injection') •
