CVE-2019-14907 – samba: Crash after failed character conversion at log level 3 or above
https://notcve.org/view.php?id=CVE-2019-14907
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). Todas las versiones de samba 4.9.x anteriores a 4.9.18, 4.10.x anteriores a 4.10.12 y 4.11.x anteriores a 4.11.5, presentan un problema donde si se configura con "log level = 3" (o superior), la cadena obtenida desde el cliente, luego de una conversión de caracteres fallida, es impresa. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00055.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14907 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4ACZVNMIFQGGXNJPMHAVBN3H2U65FXQY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GQ6U65I2K23YJC4FESW477WL55TU3PPT https: • CWE-125: Out-of-bounds Read •
