An issue was discovered in tls_verify_crl in ProFTPD through 1.3.6b. Failure to check for the appropriate field of a CRL entry (checking twice for subject, rather than once for subject and once for issuer) prevents some valid CRLs from being taken into account, and can allow clients whose certificates have been revoked to proceed with a connection to the server. Se detectó un problema en la función tls_verify_crl en ProFTPD versiones hasta 1.3.6b. Un fallo en la comprobación del campo apropiado de una entrada de CRL (verificando dos veces por tema, en lugar de una vez por tema y una vez por emisor), impide tener en cuenta algunas CRL válidas y puede permitir que clientes cuyos certificados han sido revocados continúen con una conexión en el servidor. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00009.html https://github.com/proftpd/proftpd/issues/859 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OGBBCPLJSDPFG5EI5P5G7P4KEX7YSD5G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QR65XUHPCRU3NXTSFVF2J4GWRIHC7AHW • CWE-295: Improper Certificate Validation •

ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop. ProFTPD versiones anteriores a 1.3.6b y versiones 1.3.7rc anteriores a 1.3.7rc2, permite una denegación de servicio remota no autenticada debido al manejo incorrecto de comandos demasiado largos porque el archivo main.c en un proceso secundario entra en un bucle infinito. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00009.html https://cert-portal.siemens.com/productcert/pdf/ssa-940889.pdf https://github.com/proftpd/proftpd/blob/1.3.6/NEWS https://github.com/proftpd/proftpd/blob/1.3.6/RELEASE_NOTES https://github.com/proftpd/proftpd/blob/master/NEWS https://github.com/proftpd/proftpd/blob/master/RELEASE_NOTES https://github.com/proftpd/proftpd/issues/846 https://lists.debian.org/debian-lts-announce/2019/10/msg00036.html htt • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user. ProFTPD en versiones anteriores a 1.3.5e y 1.3.6 en versiones anteriores a 1.3.6rc5 controlan si el directorio de inicio de un usuario puede contener un enlace simbólico hasta la versión de la opción de configuración AllowChrootSymlinks, pero comprueba sólo el último componente de ruta al aplicar AllowChrootSymlinks. Los atacantes con acceso local pueden omitir el control AllowChrootSymlinks reemplazando un componente de ruta (que no sea el último) con un enlace simbólico. • http://bugs.proftpd.org/show_bug.cgi?id=4295 http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00009.html http://www.securityfocus.com/bid/97409 https://github.com/proftpd/proftpd/commit/ecff21e0d0e84f35c299ef91d7fda088e516d4ed https://github.com/proftpd/proftpd/commit/f59593e6ff730b832dbe8754916cb5c821db579f https://github.com/proftpd/proftpd/pull/444/ • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

The mod_tls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman (DH) key to be used and consequently allow attackers to have unspecified impact via unknown vectors. El módulo mod_tls en ProFTPD en versiones anteriores a 1.3.5b y 1.3.6 en versiones anteriores a 1.3.6rc2 no maneja correctamente la directiva TLSDHParamFile, lo cual puede causar que se utilice una clave Diffie-Hellman (DH) más débil de lo deseado y como consecuencia permitir a atacantes tener un impacto no especificado a través de vectores desconocidos. • http://bugs.proftpd.org/show_bug.cgi?id=4230 http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179109.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179143.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179905.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00080.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00045.html http://proftpd.org/docs/NEWS-1.3.5b http://proftpd.org/docs/NEWS-1.3.6r • CWE-254: 7PK - Security Features CWE-310: Cryptographic Issues •
