CVSS: 5.3EPSS: 0%CPEs: 3EXPL: 2CVE-2021-23362 – Regular Expression Denial of Service (ReDoS)
https://notcve.org/view.php?id=CVE-2021-23362
The package hosted-git-info before 3.0.8 are vulnerable to Regular Expression Denial of Service (ReDoS) via regular expression shortcutMatch in the fromUrl function in index.js. The affected regular expression exhibits polynomial worst-case time complexity. El paquete hosted-git-info anterior a la versión 3.0.8 es vulnerable a la Denegación de Servicio por Expresión Regular (ReDoS) a través de la expresión regular shortcutMatch en la función fromUrl en index.js. La expresión regular afectada muestra una complejidad de tiempo polinómica en el peor de los casos A regular expression denial of service vulnerability was found in hosted-git-info. If an application allows user input into the affected regular expression (regexp) function, `shortcutMatch` or `fromUrl`, then an attacker could craft a regexp which takes an ever increasing amount of time to process, potentially resulting in a denial of service. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/hosted-git-info/commit/29adfe5ef789784c861b2cdeb15051ec2ba651a7 https://github.com/npm/hosted-git-info/commit/8d4b3697d79bcd89cdb36d1db165e3696c783a01 https://github.com/npm/hosted-git-info/commit/bede0dc38e1785e732bf0a48ba6f81a4a908eba3 https://github.com/npm/hosted-git-info/commits/v2 https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1088356 https://snyk.io/vuln/SNYK-JS-HOSTEDGITINFO-1088355 https://access.redhat.com/security/cve/CVE&# • CWE-400: Uncontrolled Resource Consumption CWE-1333: Inefficient Regular Expression Complexity •

ssri 5.2.2-8.0.0, fixed in 8.0.1, processes SRIs using a regular expression which is vulnerable to a denial of service. Malicious SRIs could take an extremely long time to process, leading to denial of service.

CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2021-22883 – nodejs: HTTP2 'unknownProtocol' cause DoS by resource exhaustion
https://notcve.org/view.php?id=CVE-2021-22883
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory. Node.js versiones anteriores a 10.24.0, 12.21.0, 14.16.0 y 15.10.0, es vulnerable a un ataque de denegación de servicio cuando son establecidos demasiados intentos de conexión con un "unknownProtocol". • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1043360 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ https://nodejs.org/en/blog/vulnerability/february-2021-security-releases& • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.5EPSS: 0%CPEs: 22EXPL: 1CVE-2021-22884 – nodejs: DNS rebinding in --inspect
https://notcve.org/view.php?id=CVE-2021-22884
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160. Node.js versiones anteriores a 10.24.0, 12.21.0, 14.16.0 y 15.10.0, es vulnerable a unos ataques de reenlace de DNS, ya que la lista blanca incluye “localhost6”. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1069487 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/E4FRS5ZVK4ZQ7XIJQNGIKUXG2DJFHLO7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/F45Y7TXSU33MTKB6AGL2Q5V5ZOCNPKOG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HSYFUGKFUSZ27M5TEZ3FKILWTWFJTFAZ https://nodejs.org/en/blog/vulnerability/february-2021-security-releases& • CWE-20: Improper Input Validation CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •
CVSS: 8.1EPSS: 18%CPEs: 25EXPL: 0CVE-2020-8625 – A vulnerability in BIND's GSSAPI security policy negotiation can be targeted by a buffer overflow attack
https://notcve.org/view.php?id=CVE-2020-8625
BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. • http://www.openwall.com/lists/oss-security/2021/02/19/1 http://www.openwall.com/lists/oss-security/2021/02/20/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2020-8625 https://lists.debian.org/debian-lts-announce/2021/02/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EBTPWRQWRQEJNWY4NHO4WLS4KLJ3ERHZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.or • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
