CVE-2020-14342alpinecifs-utils+126y ago09-09-2020 11:13

It was found that cifs-utils' mount.cifs was invoking a shell when requesting the Samba password, which could be used to inject arbitrary commands. An attacker able to invoke mount.cifs with special permission, such as via sudo rules, could use this flaw to escalate their privileges.CVE-2020-14383alpinesamba+45y ago02-12-2020 00:00

A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not.CVE-2020-14323alpinesamba+65y ago29-10-2020 00:00

A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before 4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of service.CVE-2020-14303alpinesamba+76y ago06-07-2020 17:12

A flaw was found in the AD DC NBT server in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4. A samba user could send an empty UDP packet to cause the samba server to crash.CVE-2020-14318alpinesamba+55y ago03-12-2020 00:00

A flaw was found in the way samba handled file and directory permissions. An authenticated user could use this flaw to gain access to certain file and directory information which otherwise would be unavailable to the attacker.CVE-2020-17049microsoftwindows server 2008 service pack 2+335y ago11-11-2020 00:00

A security feature bypass vulnerability exists in the way Key Distribution Center (KDC) determines if a service ticket can be used for delegation via Kerberos Constrained Delegation (KCD). To exploit the vulnerability, a compromised service that is configured to use KCD could tamper with a service ticket that is not valid for delegation to force the KDC to accept it. The update addresses this vulnerability by changing how the KDC validates service tickets used with KCD.CVE-2020-25722alpinesamba+64y ago18-02-2022 00:00

Multiple flaws were found in the way samba AD DC implemented access and conformance checking of stored data. An attacker could use this flaw to cause total domain compromise.CVE-2020-25719alpinesamba+734y ago18-02-2022 00:00

A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.CVE-2020-25717alpinesamba+734y ago18-02-2022 00:00

A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.CVE-2020-25721alpinesamba+34y ago16-03-2022 00:00

Kerberos acceptors need easy access to stable AD identifiers (eg objectSid). Samba as an AD DC now provides a way for Linux applications to obtain a reliable SID (and samAccountName) in issued tickets.CVE-2020-25718alpinesamba+44y ago18-02-2022 00:00

A flaw was found in the way samba, as an Active Directory Domain Controller, is able to support an RODC (read-only domain controller). This would allow an RODC to print administrator tickets.CVE-2020-27840alpinesamba+55y ago12-05-2021 14:06

A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability.CVE-2020-10704alpinesamba+176y ago06-05-2020 00:00

A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.CVE-2020-10700alpinesamba+66y ago04-05-2020 20:03

A use-after-free flaw was found in the way samba AD DC LDAP servers, handled 'Paged Results' control is combined with the 'ASQ' control. A malicious user in a samba AD could use this flaw to cause denial of service. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2.CVE-2020-10730alpinesamba+596y ago07-07-2020 13:38

A NULL pointer dereference, or possible use-after-free flaw was found in Samba AD LDAP server in versions before 4.10.17, before 4.11.11 and before 4.12.4. Although some versions of Samba shipped with Red Hat Enterprise Linux do not support Samba in AD mode, the affected code is shipped with the libldb package. This flaw allows an authenticated user to possibly trigger a use-after-free or NULL pointer dereference. The highest threat from this vulnerability is to system availability.CVE-2020-10745alpinesamba+376y ago07-07-2020 13:33

A flaw was found in all Samba versions before 4.10.17, before 4.11.11 and before 4.12.4 in the way it processed NetBios over TCP/IP. This flaw allows a remote attacker could to cause the Samba server to consume excessive CPU use, resulting in a denial of service. This highest threat from this vulnerability is to system availability.CVE-2020-10760alpinesamba+66y ago06-07-2020 18:02

A use-after-free flaw was found in all samba LDAP server versions before 4.10.17, before 4.11.11, before 4.12.4 used in a AC DC configuration. A Samba LDAP user could use this flaw to crash samba.CVE-2014-2855debianrsync+312y ago23-04-2014 14:00

The check_secret function in authenticate.c in rsync 3.1.0 and earlier allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a user name which does not exist in the secrets file.CVE-2014-0239debiansamba+212y ago28-05-2014 01:00

The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.CVE-2014-0178debiansamba+212y ago28-05-2014 01:00

Samba 3.6.6 through 3.6.23, 4.0.x before 4.0.18, and 4.1.x before 4.1.8, when a certain vfs shadow copy configuration is enabled, does not properly initialize the SRV_SNAPSHOT_ARRAY response field, which allows remote authenticated users to obtain potentially sensitive information from process memory via a (1) FSCTL_GET_SHADOW_COPY_DATA or (2) FSCTL_SRV_ENUMERATE_SNAPSHOTS request.
