In Pure-FTPd before 1.0.50, an incorrect max_filesize quota mechanism in the server allows attackers to upload files of unbounded size, which may lead to denial of service or a server hang. This occurs because a certain greater-than-zero test does not anticipate an initial -1 value. (Versions 1.0.23 through 1.0.49 are affected.) En Pure-FTPd antes de la versión 1.0.50, un mecanismo incorrecto de cuota max_filesize en el servidor permite a los atacantes subir archivos de tamaño no limitado, lo que puede llevar a la denegación de servicio o a la caída del servidor. Esto ocurre porque una determinada prueba mayor que cero no anticipa un valor inicial de -1. • https://github.com/jedisct1/pure-ftpd/commit/37ad222868e52271905b94afea4fc780d83294b4 https://github.com/jedisct1/pure-ftpd/compare/1.0.49...1.0.50 https://github.com/jedisct1/pure-ftpd/pull/158 • CWE-434: Unrestricted Upload of File with Dangerous Type •

An issue was discovered in Pure-FTPd 1.0.49. An uninitialized pointer vulnerability has been detected in the diraliases linked list. When the *lookup_alias(const char alias) or print_aliases(void) function is called, they fail to correctly detect the end of the linked list and try to access a non-existent list member. This is related to init_aliases in diraliases.c. Se detectó un problema en Pure-FTPd versión 1.0.49. • https://github.com/jedisct1/pure-ftpd/commit/8d0d42542e2cb7a56d645fbe4d0ef436e38bcefa https://lists.debian.org/debian-lts-announce/2020/02/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/22P44PECZWNDP7CMBL7NRBMNFS73C5Z2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B5NSUDWXZVWUCL6R2PTX3KBB42Z62CA5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/U5DBVHJCXWRSJPNJQCJQCKZF6ZDPZCKA https://security.gentoo.org&#x • CWE-824: Access of Uninitialized Pointer •

https://notcve.org/view.php?id=CVE-2017-12170
Downstream version 1.0.46-1 of pure-ftpd as shipped in Fedora was vulnerable to packaging error due to which the original configuration was ignored after update and service started running with default configuration. This has security implications because of overriding security-related configuration. This issue doesn't affect upstream version of pure-ftpd. La versión downstream 1.0.46-1 de pure-ftpd, tal y como viene distribuido en Fedora, es vulnerable a los errores de empaquetado ya que se ignora la configuración original después de que se actualice y que el servicio empiece a ejecutarse con la configuración por defecto. Esto provoca un impacto en la seguridad por omitir configuraciones de seguridad. • https://bugzilla.redhat.com/show_bug.cgi?id=1493114 •
