CVE-2024-0562 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more | 2024-11-23 | 7.8 High |
A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_writeback. | ||||
CVE-2023-42669 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more | 2024-11-23 | 6.5 Medium |
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-2023-4091 | 3 Fedoraproject, Redhat, Samba | 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more | 2024-11-23 | 6.5 Medium |
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-2023-3961 | 3 Fedoraproject, Redhat, Samba | 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more | 2024-11-23 | 9.1 Critical |
A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes. | ||||
CVE-2023-34967 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2024-11-22 | 5.3 Medium |
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-2023-34966 | 4 Debian, Fedoraproject, Redhat and 1 more | 7 Debian Linux, Fedora, Enterprise Linux and 4 more | 2024-11-22 | 7.5 High |
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-2023-4459 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2024-11-21 | 5.5 Medium |
A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with normal user privilege to cause a denial of service due to a missing sanity check during cleanup. | ||||
CVE-2023-4194 | 4 Debian, Fedoraproject, Linux and 1 more | 5 Debian Linux, Fedora, Linux Kernel and 2 more | 2024-11-21 | 5.5 Medium |
A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that turns out to not be accurate. | ||||
CVE-2024-0565 | 3 Linux, Netapp, Redhat | 6 Linux Kernel, Ontap Tools, Enterprise Linux and 3 more | 2024-11-21 | 6.8 Medium |
An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service. | ||||
CVE-2023-6610 | 2 Linux, Redhat | 5 Linux Kernel, Enterprise Linux, Logging and 2 more | 2024-11-21 | 7.1 High |
An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information. | ||||
CVE-2023-6606 | 2 Linux, Redhat | 8 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 5 more | 2024-11-21 | 7.1 High |
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information. | ||||
CVE-2023-6546 | 3 Fedoraproject, Linux, Redhat | 9 Fedora, Linux Kernel, Enterprise Linux and 6 more | 2024-11-21 | 7 High |
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. | ||||
