| 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 | 2025-11-20 | 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 | 2025-11-20 | 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-2023-4001 | 3 Fedoraproject, Gnu, Redhat | 4 Fedora, Grub2, Enterprise Linux and 1 more | 2025-11-20 | 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 | 2025-11-20 | 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-2024-45769 | 1 Redhat | 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more | 2025-11-20 | 5.5 Medium |
| A vulnerability was found in Performance Co-Pilot (PCP). This flaw allows an attacker to send specially crafted data to the system, which could cause the program to misbehave or crash. | ||||
| CVE-2024-45770 | 1 Redhat | 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more | 2025-11-20 | 4.4 Medium |
| A vulnerability was found in Performance Co-Pilot (PCP). This flaw can only be exploited if an attacker has access to a compromised PCP system account. The issue is related to the pmpost tool, which is used to log messages in the system. Under certain conditions, it runs with high-level privileges. | ||||
| CVE-2023-42669 | 2 Redhat, Samba | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 7 more | 2025-11-20 | 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 | 2025-11-20 | 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-2024-12243 | 1 Redhat | 5 Discovery, Enterprise Linux, Openshift and 2 more | 2025-11-20 | 5.3 Medium |
| A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition. | ||||
| CVE-2024-12133 | 1 Redhat | 5 Discovery, Enterprise Linux, Openshift and 2 more | 2025-11-20 | 5.3 Medium |
| A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack. | ||||
| CVE-2024-10041 | 2 Linux-pam, Redhat | 3 Linux-pam, Enterprise Linux, Rhel Eus | 2025-11-20 | 4.7 Medium |
| A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs, the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result in leaked passwords, such as those found in /etc/shadow while performing authentications. | ||||
| CVE-2024-1062 | 2 Fedoraproject, Redhat | 16 Fedora, 389 Directory Server, Directory Server and 13 more | 2025-11-20 | 5.5 Medium |
| A heap overflow flaw was found in 389-ds-base. This issue leads to a denial of service when writing a value larger than 256 chars in log_entry_attr. | ||||
| CVE-2024-0914 | 2 Opencryptoki Project, Redhat | 3 Opencryptoki, Enterprise Linux, Rhel Eus | 2025-11-20 | 5.9 Medium |
| A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key. | ||||
| CVE-2024-0567 | 5 Debian, Fedoraproject, Gnu and 2 more | 9 Debian Linux, Fedora, Gnutls and 6 more | 2025-11-20 | 7.5 High |
| A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack. | ||||
| CVE-2024-0553 | 3 Fedoraproject, Gnu, Redhat | 6 Fedora, Gnutls, Enterprise Linux and 3 more | 2025-11-20 | 7.5 High |
| A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981. | ||||
| CVE-2023-7192 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-11-20 | 5.5 Medium |
| A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of service (DoS) attack due to a refcount overflow. | ||||
| CVE-2023-5455 | 3 Fedoraproject, Freeipa, Redhat | 25 Fedora, Freeipa, Codeready Linux Builder and 22 more | 2025-11-20 | 6.5 Medium |
| A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt. | ||||
