Buffer overflow in the SMB1 packet chaining implementation in the chain_reply function in process.c in smbd in Samba 3.0.x before 3.3.13 allows remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a crafted field in a packet.

The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to trigger an out-of-bounds read, and cause a denial of service (process crash), via a \xff\xff security blob length in a Session Setup AndX request.

Samba 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7 does not perform range checks for file descriptors before use of the FD_SET macro, which allows remote attackers to cause a denial of service (stack memory corruption, and infinite loop or daemon crash) by opening a large number of files, related to (1) Winbind or (2) smbd.

A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndr_pull_dnsp_name contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndr_pull_dnsp_name parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation.

Stack-based buffer overflow in the (1) sid_parse and (2) dom_sid_parse functions in Samba before 3.5.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted Windows Security ID (SID) on a file share.

The internal DNS server in Samba 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4, when an AD DC is configured, allows remote authenticated users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from process memory by uploading a crafted DNS TXT record.

A vulnerability classified as problematic has been found in ppp. Affected is the function dumpppp of the file pppdump/pppdump.c of the component pppdump. The manipulation of the argument spkt.buf/rpkt.buf leads to improper validation of array index. The real existence of this vulnerability is still doubted at the moment. The name of the patch is a75fb7b198eed50d769c80c36629f38346882cbf. It is recommended to apply a patch to fix this issue. VDB-216198 is the identifier assigned to this vulnerability. NOTE: pppdump is not used in normal process of setting up a PPP connection, is not installed setuid-root, and is not invoked automatically in any scenario.

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.

Heap-based buffer overflow in process.c in smbd in Samba 3.0, as used in the file-sharing service on the BlackBerry PlayBook tablet before 2.0.0.7971 and other products, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a Batched (aka AndX) request that triggers infinite recursion.

Buffer overflow in rsync 2.6.9 to 3.0.1, with extended attribute (xattr) support enabled, might allow remote attackers to execute arbitrary code via unknown vectors.

Stack-based buffer overflow in the send_mailslot function in nmbd in Samba 3.0.0 through 3.0.27a, when the "domain logons" option is enabled, allows remote attackers to execute arbitrary code via a GETDC mailslot request composed of a long GETDC string following an offset username in a SAMLOGON logon request.

Stack-based buffer overflow in the reply_netbios_packet function in nmbd/nmbd_packets.c in nmbd in Samba 3.0.0 through 3.0.26a, when operating as a WINS server, allows remote attackers to execute arbitrary code via crafted WINS Name Registration requests followed by a WINS Name Query request.

Stack-based buffer overflow in nmbd in Samba 3.0.0 through 3.0.26a, when configured as a Primary or Backup Domain controller, allows remote attackers to have an unknown impact via crafted GETDC mailslot requests, related to handling of GETDC logon server requests.

Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2 (lsa_io_trans_names).

Heap-based buffer overflow in the dcerpc_read_ncacn_packet_done function in librpc/rpc/dcerpc_util.c in winbindd in Samba 3.x before 3.6.22, 4.0.x before 4.0.13, and 4.1.x before 4.1.3 allows remote AD domain controllers to execute arbitrary code via an invalid fragment length in a DCE-RPC packet.

Heap-based buffer overflow in the receive_smb_raw function in util/sock.c in Samba 3.0.0 through 3.0.29 allows remote attackers to execute arbitrary code via a crafted SMB response.

Samba before 2.2.5 does not properly terminate the enum_csc_policy data structure, which may allow remote attackers to execute arbitrary code via a buffer overflow attack.

Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory.

rsync 3.x before 3.0.8, when certain recursion, deletion, and ownership options are used, allows remote rsync servers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via malformed data.

There is a stack-based buffer overflow on some Tenda routers (FH1202/F1202/F1200: versions before 1.2.0.20). Crafted POST requests to an unspecified URL result in DoS, interrupting the HTTP service (used to login to the web UI of a router) for 1 to 2 seconds.

A vulnerability classified as problematic was found in MindSpore 2.0.0-alpha/2.0.0-rc1. This vulnerability affects the function JsonHelper::UpdateArray of the file mindspore/ccsrc/minddata/dataset/util/json_helper.cc. The manipulation leads to memory corruption. The name of the patch is 30f4729ea2c01e1ed437ba92a81e2fc098d608a9. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-230176.

The ABB IDAL FTP server is vulnerable to a buffer overflow when a long string is sent by an authenticated attacker. This overflow is handled, but terminates the process. An authenticated attacker can send a FTP command string of 472 bytes or more to overflow a buffer, causing an exception that terminates the server.
