Description
This security bulletin contains information about 46 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2023-1194)
The vulnerability allows a remote user to read data or crash the application.
An out-of-bounds (OOB) memory read flaw was found in parse_lease_state in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. When an attacker sends the CREATE command with a malformed payload to KSMBD, due to a missing check of `NameOffset` in the `parse_lease_state()` function, the `create_context` object can access invalid memory.
2) Race condition (CVE-ID: CVE-2023-32254)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a race condition within fs/ksmbd/mgmt/tree_connect.c in ksmbd in Linux kernel when processing SMB2_TREE_DISCONNECT commands. A remote attacker can trigger a use-after-free error using concurrent smb2 tree disconnect requests and execute arbitrary code on the system.
3) Race condition (CVE-ID: CVE-2023-32258)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a race condition when processing SMB2_LOGOFF and SMB2_CLOSE commands in ksmbd. A remote attacker can send specially crafted data to the server and execute arbitrary code on the system.
4) Integer overflow (CVE-ID: CVE-2023-38427)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
