Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2023-6606)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a boundary condition within the smbCalcSize() function in fs/smb/client/netmisc.c file. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.
2) NULL pointer dereference (CVE-ID: CVE-2023-6535)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_execute_request() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.
3) Out-of-bounds read (CVE-ID: CVE-2023-6610)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a boundary condition within the smb2_dump_detail() function in fs/smb/client/smb2ops.c. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.
4) Improper locking (CVE-ID: CVE-2023-2269)
The vulnerability allows a local user to perform a denial of service attack (DoS).
The vulnerability exists due to double-locking error in table_clear in drivers/md/dm-ioctl.c. A local user can perform a denial of service (DoS) attack.
5) NULL pointer dereference (CVE-ID: CVE-2023-6356)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the nvmet_tcp_build_iovec() function in the Linux kernel's NVMe driver. A remote attacker can pass specially crafted TCP packets to the system and perform a denial of service (DoS) attack.
6) Use-after-free (CVE-ID: CVE-2023-4623)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the the Linux kernel net/sched: sch_hfsc (HFSC qdisc traffic control) component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
7) NULL pointer dereference (CVE-ID: CVE-2023-6536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the __nvmet_req_complete() function in the Linux kernel's NVMe driver. A remote attacker can send specially crafted NVMe-oF/TCP packets to the system and perform a denial of service (DoS) attack.
8) Use-after-free (CVE-ID: CVE-2023-4921)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the qfq_dequeue() function within the the Linux kernel's net/sched: sch_qfq component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
9) Improper access control (CVE-ID: CVE-2023-46813)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses. A local user can gain arbitrary write access to kernel memory and execute arbitrary code with elevated privileges.
10) Out-of-bounds write (CVE-ID: CVE-2024-0646)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input in the Linux kernel’s Transport Layer Security functionality in the way a user calls a function splice with a ktls socket as the destination. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
11) OS Command Injection (CVE-ID: CVE-2023-51385)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing user names, if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. A remote attacker can execute arbitrary OS commands via an untrusted Git repository.
12) Use-after-free (CVE-ID: CVE-2023-6817)
The vulnerability allows a local authenticated user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.
13) Out-of-bounds write (CVE-ID: CVE-2023-5717)
The vulnerability local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the Linux kernel's Linux Kernel Performance Events (perf) component. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
14) Use-after-free (CVE-ID: CVE-2023-1838)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
15) Use-after-free (CVE-ID: CVE-2023-40283)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the l2cap_sock_release() function in net/bluetooth/l2cap_sock.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
16) NULL pointer dereference (CVE-ID: CVE-2023-2166)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in net/can/af_can.c when processing CAN frames. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
17) Inadequate encryption strength (CVE-ID: CVE-2023-48795)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.
The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.
