CVE-2023-32252
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2LOGOFF commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to creat...
CVE-2023-32257 Session race condition remote code execution vulnerability
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2SESSIONSETUP and SMB2LOGOFF commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage th...
CVE-2023-32247
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2SESSIONSETUP commands. The issue results from the lack of control of resource consumption. An attacker can leverage this vulnerability to create a...
CVE-2023-32247 Session setup memory exhaustion denial-of-service vulnerability
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2SESSIONSETUP commands. The issue results from the lack of control of resource consumption. An attacker can leverage this vulnerability to create a...
CVE-2023-32247
CVE-2023-32247 affects the Linux kernel ksmbd SMB server. The flaw is in SMB2_SESSION_SETUP handling and stems from lack of resource-control, enabling a remote attacker to trigger a denial-of-service (A: HIGH, CVSS 3.1: 7.5). The issue is exploitable over network with no privileges required and n...
The vulnerability of the `ksmbd_verify_smb_message()` function in the `fs/smb/server/smb_common.c` file of the KSMBD file system of the Linux operating system allows a attacker to access protected information or cause service failures.
The vulnerability of the ksmbdverifysmbmessage function in the fs/smb/server/smbcommon.c file of the KSMBD file system in the Linux operating system is related to the lack of control over the request identifier. Exploiting this vulnerability could allow a remote attacker to access protected...
The vulnerability of the `ksmbd_conn_handler_loop()` function in the `fs/smb/server/connection.c` file of the KSMBD file system of the Linux operating system allows a attacker to access protected information or cause service failures.
The vulnerability of the ksmbdconnhandlerloop function in the fs/smb/server/connection.c file of the KSMBD file system of the Linux operating system is related to reading data beyond the allocated buffer. Exploiting this vulnerability can allow an attacker to access protected information or cause...
Denial Of Service (DoS)
tcpdump is vulnerable to Denial Of Service DoS. The vulnerability exists due to the out-of-bounds write in the SMB protocol decoder when decoding a crafted network packet, allowing an attacker to cause an application crash...
SUSE CVE-2023-3347
A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured "server signing = required" or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, suc...
USN-6238-1: Samba vulnerabilities
It was discovered that Samba incorrectly handled Winbind NTLM authentication responses. An attacker could possibly use this issue to cause Samba to crash, resulting in a denial of service. CVE-2022-2127 Andreas Schneider discovered that Samba incorrectly enforced SMB2 packet signing. A remote...
