CVSS: 7.5EPSS: 0%CPEs: 10EXPL: 0CVE-2020-10663 – rubygem-json: Unsafe object creation vulnerability in JSON
https://notcve.org/view.php?id=CVE-2020-10663
The JSON gem through 2.2.0 for Ruby, as used in Ruby 2.4 through 2.4.9, 2.5 through 2.5.7, and 2.6 through 2.6.5, has an Unsafe Object Creation Vulnerability. This is quite similar to CVE-2013-0269, but does not rely on poor garbage-collection behavior within Ruby. Specifically, use of JSON parsing methods can lead to creation of a malicious object within the interpreter, with adverse effects that are application-dependent. La gema JSON versiones hasta 2.2.0 para Ruby, como es usado en Ruby versiones 2.4 hasta 2.4.9, versiones 2.5 hasta 2.5.7 y versiones 2.6 hasta 2.6.5, tiene una Vulnerabilidad de Creación de Objetos No Segura. Esto es bastante similar a CVE-2013-0269, pero no se basa en un comportamiento inapropiado garbage-collection dentro de Ruby. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00004.html http://seclists.org/fulldisclosure/2020/Dec/32 https://lists.apache.org/thread.html/r37c0e1807da7ff2bdd028bbe296465a6bbb99e2320dbe661d5d8b33b%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r3b04f4e99a19613f88ae088aa18cd271231a3c79dfff8f5efa8cda61%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r5f17bfca1d6e7f4b33ae978725b2fd62a9f1b3111696eafa9add802d%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r8d2e174230f6d26e16c0 • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 7.5EPSS: 1%CPEs: 11EXPL: 0CVE-2020-5247 – HTTP Response Splitting in Puma
https://notcve.org/view.php?id=CVE-2020-5247
In Puma (RubyGem) before 4.3.2 and before 3.12.3, if an application using Puma allows untrusted input in a response header, an attacker can use newline characters (i.e. `CR`, `LF` or`/r`, `/n`) to end the header and inject malicious content, such as additional headers or an entirely new response body. This vulnerability is known as HTTP Response Splitting. While not an attack in itself, response splitting is a vector for several other attacks, such as cross-site scripting (XSS). This is related to CVE-2019-16254, which fixed this vulnerability for the WEBrick Ruby web server. • https://github.com/puma/puma/security/advisories/GHSA-84j7-475p-hp8v https://lists.debian.org/debian-lts-announce/2022/05/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BMJ3CGZ3DLBJ5WUUKMI5ZFXFJQMXJZIK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DIHVO3CQMU7BZC7FCTSRJ33YDNS3GFPK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NJ3LL5F5QADB6LM46GXZETREAKZMQNRD https://owasp.org/www-communi • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •

https://notcve.org/view.php?id=CVE-2016-2338
An exploitable heap overflow vulnerability exists in the Psych::Emitter start_document function of Ruby. In Psych::Emitter start_document function heap buffer "head" allocation is made based on tags array length. Specially constructed object passed as element of tags array can increase this array size after mentioned allocation and cause heap overflow. Se presenta una vulnerabilidad de desbordamiento de pila explotable en la función Psych::Emitter start_document de Ruby. En la función Psych::Emitter start_document la asignación de "head" del buffer de heap es realizada en base a la longitud del array de etiquetas. • https://github.com/SpiralBL0CK/CVE-2016-2338-nday http://www.talosintelligence.com/reports/TALOS-2016-0032 https://lists.debian.org/debian-lts-announce/2020/03/msg00032.html https://security.netapp.com/advisory/ntap-20221228-0005 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-15845
Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions. Ruby versiones hasta 2.4.7, versiones 2.5.x hasta 2.5.6 y versiones 2.6.x hasta 2.6.4, maneja inapropiadamente la comprobación de ruta dentro de las funciones File.fnmatch. A flaw was discovered in Ruby in the way certain functions handled strings containing NULL bytes. Specifically, the built-in methods File.fnmatch and its alias File.fnmatch? did not properly handle path patterns containing the NULL byte. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00041.html https://hackerone.com/reports/449617 https://lists.debian.org/debian-lts-announce/2019/11/msg00025.html https://seclists.org/bugtraq/2019/Dec/31 https://seclists.org/bugtraq/2019/Dec/32 https://security.gentoo.org/glsa/202003-06 https://usn.ubuntu.com/4201-1 https://www.debian.org/security/2019/dsa-4587 https://www.oracle.com/security-alerts/cpujan2020.html https://access.redhat.com/security/cve • CWE-41: Improper Resolution of Path Equivalence •
