CVSS: 9.8EPSS: 0%CPEs: 29EXPL: 1CVE-2017-14064 – ruby: Arbitrary heap exposure during a JSON.generate call
https://notcve.org/view.php?id=CVE-2017-14064
Ruby through 2.2.7, 2.3.x through 2.3.4, and 2.4.x through 2.4.1 can expose arbitrary memory during a JSON.generate call. The issues lies in using strdup in ext/json/ext/generator/generator.c, which will stop after encountering a '\0' byte, returning a pointer to a string of length zero, which is not the length stored in space_len. Ruby hasta la versión 2.2.7, 2.3.x hasta la 2.3.4, y 2.4.x hasta la 2.4.1 puede exponer memoria arbitraria durante una llamada JSON.generate. Los problemas surgen al usar strdup en ext/json/ext/generator/generator.c, el cual se detendría después de encontrar un byte '\0', devolviendo un puntero a un string de longitud cero, que no es la longitud almacenada en space_len. A buffer overflow vulnerability was found in the JSON extension of ruby. • http://www.securityfocus.com/bid/100890 http://www.securitytracker.com/id/1039363 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2017:3485 https://access.redhat.com/errata/RHSA-2018:0378 https://access.redhat.com/errata/RHSA-2018:0583 https://access.redhat.com/errata/RHSA-2018:0585 https://bugs.ruby-lang.org/issues/13853 https://github.com/flori/json/commit/8f782fd8e181d9cfe9387ded43a5ca9692266b85 https://hackerone.com/reports/209949 https://lists. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 10.0EPSS: 0%CPEs: 13EXPL: 0CVE-2017-1000116 – mercurial: command injection on clients through malicious ssh URLs
https://notcve.org/view.php?id=CVE-2017-1000116
Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks. Las versiones anteriores a la 4.3 de Mercurial no sanitizaban adecuadamente los nombres de host pasados a ssh, lo que conducía a posibles ataques de inyección de shell. A shell command injection flaw related to the handling of "ssh" URLs has been discovered in Mercurial. This can be exploited to execute shell commands with the privileges of the user running the Mercurial client, for example, when performing a "checkout" or "update" action on a sub-repository within a malicious repository or a legitimate repository containing a malicious commit. • http://www.debian.org/security/2017/dsa-3963 http://www.securityfocus.com/bid/100290 https://access.redhat.com/errata/RHSA-2017:2489 https://security.gentoo.org/glsa/201709-18 https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.3_.2F_4.3.1_.282017-08-10.29 https://access.redhat.com/security/cve/CVE-2017-1000116 https://bugzilla.redhat.com/show_bug.cgi?id=1479915 • CWE-20: Improper Input Validation CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2017-1000115
Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositories to modify files outside the repository Las versiones anteriores a la 4.3 de Mercurial son vulnerables a una falta de comprobación de symlink. Los repositorios maliciosos pueden aprovecharse de esto para modificar archivos fuera del repositorio. A vulnerability was found in the way Mercurial handles path auditing and caches the results. An attacker could abuse a repository with a series of commits mixing symlinks and regular files/directories to trick Mercurial into writing outside of a given repository. • http://www.debian.org/security/2017/dsa-3963 http://www.securityfocus.com/bid/100290 https://access.redhat.com/errata/RHSA-2017:2489 https://security.gentoo.org/glsa/201709-18 https://www.mercurial-scm.org/wiki/WhatsNew#Mercurial_4.3_.2F_4.3.1_.282017-08-10.29 https://access.redhat.com/security/cve/CVE-2017-1000115 https://bugzilla.redhat.com/show_bug.cgi?id=1480330 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2017-10664
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. qemu-nbd en QEMU (Quick Emulator) no ignora la señal SIGPIPE, lo que permite a atacantes remotos provocar una denegación de servicio desconectando el proceso durante un intento de respuesta de servidor a cliente. Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a Denial of Service (DoS). • http://www.debian.org/security/2017/dsa-3920 http://www.openwall.com/lists/oss-security/2017/06/29/1 http://www.securityfocus.com/bid/99513 https://access.redhat.com/errata/RHSA-2017:2390 https://access.redhat.com/errata/RHSA-2017:2445 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RH • CWE-248: Uncaught Exception •
