CVE-2021-31799 – rubygem-rdoc: Command injection vulnerability in RDoc
https://notcve.org/view.php?id=CVE-2021-31799
In RDoc 3.11 through 6.x before 6.3.1, as distributed with Ruby through 3.0.1, it is possible to execute arbitrary code via | and tags in a filename. En RDoc versiones 3.11 hasta 6.x versiones anteriores a 6.3.1, como se distribuye con Ruby versiones hasta 3.0.1, es posible ejecutar código arbitrario por medio de | y etiquetas en un nombre de archivo An operating system command injection flaw was found in RDoc. Using the rdoc command to generate documentation for a malicious Ruby source code could lead to execution of arbitrary commands with the privileges of the user running rdoc. • https://lists.debian.org/debian-lts-announce/2021/10/msg00009.html https://security-tracker.debian.org/tracker/CVE-2021-31799 https://security.gentoo.org/glsa/202401-05 https://security.netapp.com/advisory/ntap-20210902-0004 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.ruby-lang.org/en/news/2021/05/02/os-command-injection-in-rdoc https://access.redhat.com/security/cve/CVE-2021-31799 https://bugzilla.redhat.com/show_bug.cgi?id=1980132 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2021-31810 – ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host
https://notcve.org/view.php?id=CVE-2021-31810
An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions). Se ha detectado un problema en Ruby versiones hasta 2.6.7, versiones 2.7.x hasta 2.7.3, y versiones 3.x hasta 3.0.1. Un servidor FTP malicioso puede usar la respuesta PASV para engañar a la función Net::FTP para que se conecte de nuevo a una dirección IP y un puerto determinados. • https://hackerone.com/reports/1145454 https://lists.debian.org/debian-lts-announce/2021/10/msg00009.html https://lists.debian.org/debian-lts-announce/2023/04/msg00033.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MWXHK5UUHVSHF7HTHMX6JY3WXDVNIHSL https://security.gentoo.org/glsa/202401-27 https://security.netapp.com/advisory/ntap-20210917-0001 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.ruby-lang.org/en/news/2021/07/07/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •
