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 •

CVE-2019-14861

https://notcve.org/view.php?id=CVE-2019-14861

All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the name of the zone, the ldb_qsort() and dns_name_compare() routines could be confused into reading memory prior to the list of DNS entries when responding to DnssrvEnumRecords() or DnssrvEnumRecords2() and so following invalid memory as a pointer. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html http://www.openwall.com/lists/oss-security/2024/06/24/3 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14861 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PJH3ROOFYMOATD2UEPC47P5RPBDTY77E https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WNKA4YIPV7AZR7KK3GW6L3HKGHSGJZFE https:/&#x • CWE-276: Incorrect Default Permissions •
