CVE-2024-9355 1 Redhat 22 Amq Streams, Ansible Automation Platform, Container Native Virtualization and 19 more 2025-08-30 6.5 Medium
A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.

CVE-2023-42669 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more 2025-08-30 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-2023-40551 2 Fedoraproject, Redhat 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2025-08-30 5.1 Medium
A flaw was found in the MZ binary format in Shim. An out-of-bounds read may occur, leading to a crash or possible exposure of sensitive data during the system's boot phase.
CVE-2023-40550 2 Fedoraproject, Redhat 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2025-08-30 5.5 Medium
An out-of-bounds read flaw was found in Shim when it tried to validate the SBAT information. This issue may expose sensitive data during the system's boot phase.
CVE-2023-40549 2 Fedoraproject, Redhat 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2025-08-30 6.2 Medium
An out-of-bounds read flaw was found in Shim due to the lack of proper boundary verification during the load of a PE binary. This flaw allows an attacker to load a crafted PE binary, triggering the issue and crashing Shim, resulting in a denial of service.
CVE-2023-40548 2 Fedoraproject, Redhat 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2025-08-30 7.4 High
A buffer overflow was found in Shim in the 32-bit system. The overflow happens due to an addition operation involving a user-controlled value parsed from the PE binary being used by Shim. This value is further used for memory allocation operations, leading to a heap-based buffer overflow. This flaw causes memory corruption and can lead to a crash or data integrity issues during the boot phase.
CVE-2023-40546 2 Fedoraproject, Redhat 7 Fedora, Enterprise Linux, Rhel Aus and 4 more 2025-08-30 6.2 Medium
A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a crash under certain circumstances.
CVE-2023-4091 3 Fedoraproject, Redhat, Samba 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more 2025-08-30 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-2023-4001 3 Fedoraproject, Gnu, Redhat 4 Fedora, Grub2, Enterprise Linux and 1 more 2025-08-30 6.8 Medium
An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package.
CVE-2023-3961 3 Fedoraproject, Redhat, Samba 7 Fedora, Enterprise Linux, Enterprise Linux Eus and 4 more 2025-08-30 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-2023-34968 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 5.3 Medium
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-2023-34967 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 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 2025-08-30 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-2022-2127 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux and 4 more 2025-08-30 5.9 Medium
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-2023-6816 4 Debian, Fedoraproject, Redhat and 1 more 13 Debian Linux, Fedora, Enterprise Linux and 10 more 2025-08-29 9.8 Critical
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.
