https://notcve.org/view.php?id=CVE-2021-27290
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. This issue only affects consumers using the strict option. ssri versión 5.2.2-8.0.0, corregido en versión 8.0.1, procesa los SRI usando una expresión regular que es vulnerable a una denegación de servicio. Los SRI maliciosos pueden tardar mucho en procesarse, conllevando a una denegación del servicio. Este problema solo afecta a consumidores que usan la opción estricta A flaw was found in ssri package. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://doyensec.com/resources/Doyensec_Advisory_ssri_redos.pdf https://github.com/yetingli/SaveResults/blob/main/pdf/ssri-redos.pdf https://npmjs.com https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-27290 https://bugzilla.redhat.com/show_bug.cgi?id=1941471 • CWE-770: Allocation of Resources Without Limits or Throttling •
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') •
CVSS: 8.1EPSS: 0%CPEs: 10EXPL: 1CVE-2020-8265 – nodejs: use-after-free in the TLS implementation
https://notcve.org/view.php?id=CVE-2020-8265
Node.js versions before 10.23.1, 12.20.1, 14.15.4, 15.5.1 are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits. Node.js versiones anteriores a 10.23.1, 12.20.1, 14.15.4, 15.5.1, son vulnerables a un bug de uso de la memoria previamente liberada en su implementación TLS. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/988103 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/H472D5HPXN6RRXCNFML3BK5OYC52CXF2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/K4I6MZNC7C7VIDQR267OL4TVCI3ZKAC4 https://nodejs.org/en/blog/vulnerability/january-2021-security-releases https://security.gentoo.org/glsa/202101-07 https://security.netapp.com/advisory/ntap-20210212-0003 https:&# • CWE-416: Use After Free •
