The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - samba: Symlink race error can allow directory creation outside of the exported share (CVE-2021-43566)

  - samba: Validated dnsHostname write right needs to be implemented (CVE-2022-32743)

  - A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated     attacker with permissions to read or modify share metadata, to perform this operation outside of the     share. (CVE-2021-20316)

  - In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. (CVE-2022-1615)

  - An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in     winbindd_pam_auth_crap.c. When performing NTLM authentication, the client replies to cryptographic     challenges back to the server. These replies have variable lengths, and Winbind fails to check the lan     manager response length. When Winbind is used for NTLM authentication, a maliciously crafted request can     trigger an out-of-bounds read in Winbind, possibly resulting in a crash. (CVE-2022-2127)

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client     had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or     printer) instead of client-supplied data. The client cannot control the area of the server memory written     to the file (or printer). (CVE-2022-32742)

  - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP     message values freed by a preceding database module, resulting in a use-after-free issue. This issue is     only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

  - An infinite loop vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing     Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function sl_unpack_loop() did not     validate a field in the network packet that contains the count of elements in an array-like structure. By     passing 0 as the count value, the attacked function will run in an endless loop consuming 100% CPU. This     flaw allows an attacker to issue a malformed RPC request, triggering an infinite loop, resulting in a     denial of service condition. (CVE-2023-34966)

  - A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. When parsing     Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys     are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a     lack of type checking in callers of the dalloc_value_for_key() function, which returns the object     associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the     passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client     connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker     process, affecting all other clients this worker serves. (CVE-2023-34967)

  - A path disclosure vulnerability was found in Samba. As part of the Spotlight protocol, Samba discloses the     server-side absolute path of shares, files, and directories in the results for search queries. This flaw     allows a malicious client or an attacker with a targeted RPC request to view the information that is part     of the disclosed path. (CVE-2023-34968)

  - A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with     read-only permissions when the Samba VFS module acl_xattr is configured with acl_xattr:ignore system     acls = yes. The SMB protocol allows opening files when the client requests read-only access but then     implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create     disposition request. The issue arises in configurations that bypass kernel file system permissions checks,     relying solely on Samba's permissions. (CVE-2023-4091)

  - A vulnerability was found in Samba's rpcecho development server, a non-Windows RPC server used to test     Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked     indefinitely. The issue arises because the rpcecho service operates with only one worker in the main RPC     task, allowing calls to the rpcecho server to be blocked for a specified time, causing service     disruptions. This disruption is triggered by a sleep() call in the dcesrv_echo_TestSleep() function     under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls     to the rpcecho server, requesting it to block for a specified duration, effectively disrupting most     services and leading to a complete denial of service on the AD DC. The DoS affects all other services as     rpcecho runs in the main RPC task. (CVE-2023-42669)

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - samba: Active Directory (AD) domain user could become root on domain members (CVE-2020-25717)

  - samba: RC4/HMAC-MD5 NetLogon Secure Channel is weak and should be avoided (CVE-2022-38023)

  - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to     retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
    (CVE-2016-2124)

  - A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption     with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to     any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-     middle attack. (CVE-2017-12151)

  - Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of     the server to clear allocated heap memory. (CVE-2017-15275)

  - smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic     infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks.
    (CVE-2017-9461)

  - A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a     malicious server can supply a pathname to the client with separators. This could allow the client to     access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to     create files outside of the current working directory using the privileges of the client user.
    (CVE-2019-10218)

  - A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API.
    An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix     permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6     and 4.10.2 are vulnerable. (CVE-2019-3880)

  - 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-2020-10730)

  - 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-2020-14318)

  - 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-2020-14323)

  - A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix     group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end     of the array in the case where a negative cache entry had been added to the mapping cache. This could     cause the calling code to return those values into the process token that stores the group membership for     a user. The highest threat from this vulnerability is to data confidentiality and integrity.
    (CVE-2021-20254)

  - A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to     an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The     highest threat from this vulnerability is to system availability. (CVE-2021-20277)

  - A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated     attacker with permissions to read or modify share metadata, to perform this operation outside of the     share. (CVE-2021-20316)

  - All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to     allow a directory to be created in an area of the server file system not exported under the share     definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack     to succeed. (CVE-2021-43566)

  - In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. (CVE-2022-1615)

  - An out-of-bounds read vulnerability was found in Samba due to insufficient length checks in     winbindd_pam_auth_crap.c.

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-032 advisory.

 - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
 (CVE-2016-2124)

 - 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-2020-17049)

 - A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated attacker with permissions to read or modify share metadata, to perform this operation outside of the share. (CVE-2021-20316)

 - All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled, or the share also available via NFS in order for this attack to succeed. (CVE-2021-43566)

 - All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
 (CVE-2021-44141)

 - The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an account modification re-adds an SPN that was previously present on that account, such as one added when a computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an attacker who can intercept traffic can impersonate existing services, resulting in a loss of confidentiality and integrity. (CVE-2022-0336)

 - In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. (CVE-2022-1615)

 - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). (CVE-2022-32742)

 - Samba does not validate the Validated-DNS-Host-Name right for the dNSHostName attribute which could permit unprivileged users to write it. (CVE-2022-32743)

 - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP message values freed by a preceding database module, resulting in a use-after-free issue. This issue is only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

 - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

 - A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside the 'smbd' configured share path and gain access to another restricted server's filesystem.
 (CVE-2022-3592)

 - Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability (CVE-2022-37966)

 - Windows Kerberos Elevation of Privilege Vulnerability (CVE-2022-37967)

 - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

 - Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov 8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts- hmac-sha1-96). (CVE-2022-45141)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202309-06 (Samba: Multiple Vulnerabilities)

  - Directory traversal vulnerability in the (1) extract and (2) extractall functions in the tarfile module in     Python allows user-assisted remote attackers to overwrite arbitrary files via a .. (dot dot) sequence in     filenames in a TAR archive, a related issue to CVE-2001-1267. (CVE-2007-4559)

  - A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to     retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
    (CVE-2016-2124)

  - Kerberos Security Feature Bypass Vulnerability (CVE-2020-17049)

  - 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-2020-25717)

  - 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-2020-25718)

  - 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-2020-25719)

  - 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-2020-25721)

  - 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-2020-25722)

  - MaxQueryDuration not honoured in Samba AD DC LDAP (CVE-2021-3670)

  - In DCE/RPC it is possible to share the handles (cookies for resource state) between multiple connections     via a mechanism called 'association groups'. These handles can reference connections to our sam.ldb     database. However while the database was correctly shared, the user credentials state was only pointed at,     and when one connection within that association group ended, the database would be left pointing at an     invalid 'struct session_info'. The most likely outcome here is a crash, but it is possible that the use-     after-free could instead allow different user state to be pointed at and this might allow more privileged     access. (CVE-2021-3738)

  - A flaw was found in samba. A race condition in the password lockout code may lead to the risk of brute     force attacks being successful if special conditions are met. (CVE-2021-20251)

  - A flaw was found in the way Samba handled file/directory metadata. This flaw allows an authenticated     attacker with permissions to read or modify share metadata, to perform this operation outside of the     share. (CVE-2021-20316)

  - A flaw was found in the way samba implemented DCE/RPC. If a client to a Samba server sent a very large     DCE/RPC request, and chose to fragment it, an attacker could replace later fragments with their own data,     bypassing the signature requirements. (CVE-2021-23192)

  - All versions of Samba prior to 4.15.5 are vulnerable to a malicious client using a server symlink to     determine if a file or directory exists in an area of the server file system not exported under the share     definition. SMB1 with unix extensions has to be enabled in order for this attack to succeed.
    (CVE-2021-44141)

  - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide ...enhanced compatibility     with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver. Samba versions prior to     4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via     specially crafted extended file attributes. A remote attacker with write access to extended file     attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

  - The Samba AD DC includes checks when adding service principals names (SPNs) to an account to ensure that     SPNs do not alias with those already in the database. Some of these checks are able to be bypassed if an     account modification re-adds an SPN that was previously present on that account, such as one added when a     computer is joined to a domain. An attacker who has the ability to write to an account can exploit this to     perform a denial-of-service attack by adding an SPN that matches an existing service. Additionally, an     attacker who can intercept traffic can impersonate existing services, resulting in a loss of     confidentiality and integrity. (CVE-2022-0336)

  - In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values. (CVE-2022-1615)

  - A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a     single account and set of keys, allowing them to decrypt each other's tickets. A user who has been     requested to change their password, can exploit this flaw to obtain and use tickets to other services.
    (CVE-2022-2031)

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - A symlink following vulnerability was found in Samba, where a user can create a symbolic link that will     make 'smbd' escape the configured share path. This flaw allows a remote user with access to the exported     part of the file system under a share via SMB1 unix extensions or NFS to create symlinks to files outside     the 'smbd' configured share path and gain access to another restricted server's filesystem.
    (CVE-2022-3592)

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client     had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or     printer) instead of client-supplied data. The client cannot control the area of the server memory written     to the file (or printer). (CVE-2022-32742)

  - Samba does not validate the Validated-DNS-Host-Name right for the dNSHostName attribute which could permit     unprivileged users to write it. (CVE-2022-32743)

  - A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By     encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling     full domain takeover. (CVE-2022-32744)

  - A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP     add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

  - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP     message values freed by a preceding database module, resulting in a use-after-free issue. This issue is     only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

  - Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability (CVE-2022-37966)

  - Windows Kerberos Elevation of Privilege Vulnerability (CVE-2022-37967)

  - Netlogon RPC Elevation of Privilege Vulnerability (CVE-2022-38023)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
    (CVE-2022-42898)

  - Since the Windows Kerberos RC4-HMAC Elevation of Privilege Vulnerability was disclosed by Microsoft on Nov     8 2022 and per RFC8429 it is assumed that rc4-hmac is weak, Vulnerable Samba Active Directory DCs will     issue rc4-hmac encrypted tickets despite the target server supporting better encryption (eg aes256-cts-     hmac-sha1-96). (CVE-2022-45141)

  - A flaw was found in Samba. An incomplete access check on dnsHostName allows authenticated but otherwise     unprivileged users to delete this attribute from any object in the directory. (CVE-2023-0225)

  - The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919 Confidential attribute disclosure vi LDAP     filters was insufficient and an attacker may be able to obtain confidential BitLocker recovery keys from a     Samba AD DC. (CVE-2023-0614)

  - The Samba AD DC administration tool, when operating against a remote LDAP server, will by default send new     or reset passwords over a signed-only connection. (CVE-2023-0922)
