RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications to cause a denial of service attack against RubyGems clients who have issued a `query` command. RubyGems 2.6.12 y anteriores es vulnerable a especificaciones de gemas manipuladas maliciosamente para provocar ataques de denegación de servicio contra clientes RubyGems que hayan enviado un comando query. It was found that rubygems could use an excessive amount of CPU while parsing a sufficiently long gem summary. A specially crafted gem from a gem repository could freeze gem commands attempting to parse its summary. • http://blog.rubygems.org/2017/08/27/2.6.13-released.html http://www.securityfocus.com/bid/100579 http://www.securitytracker.com/id/1039249 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://github.com/rubygems/rubygems/commit/8a38a4fc24c6591e6c8f43d1fadab6efeb4d6251 https://hackerone.com/reports/243003 https://lists.debian.org/debian- • CWE-20: Improper Input Validation CWE-138: Improper Neutralization of Special Elements •

RubyGems version 2.6.12 and earlier fails to validate specification names, allowing a maliciously crafted gem to potentially overwrite any file on the filesystem. RubyGems 2.6.12 y anteriores no valida con éxito los nombres de las especificaciones, permitiendo que una gema manipulada maliciosamente sobrescriba cualquier archivo en el sistema de archivos. It was found that rubygems did not sanitize gem names during installation of a given gem. A specially crafted gem could use this flaw to install files outside of the regular directory. RubyGems versions prior to 2.6.13 suffer from an arbitrary file overwrite vulnerability. • https://www.exploit-db.com/exploits/42611 http://blog.rubygems.org/2017/08/27/2.6.13-released.html http://www.securityfocus.com/bid/100580 http://www.securitytracker.com/id/1039249 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://github.com/rubygems/rubygems/commit/ad5c0a53a86ca5b218c7976765c0365b91d22cb2 https://hackerone.com/repor • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-138: Improper Neutralization of Special Elements •
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') •

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.
