A vulnerability was found in libXpm due to a boundary condition within the XpmCreateXpmImageFromBuffer() function. This flaw allows a local attacker to trigger an out-of-bounds read error and read the contents of memory on the system.
CVE-2023-43787 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2026-06-17 N/A 7.8 HIGH
A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.
CVE-2023-43786 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2026-06-17 N/A 5.5 MEDIUM
A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
CVE-2023-43785 3 Fedoraproject, Redhat, X.org 3 Fedora, Enterprise Linux, Libx11 2026-06-17 N/A 6.5 MEDIUM
A vulnerability was found in libX11 due to a boundary condition within the _XkbReadKeySyms() function. This flaw allows a local user to trigger an out-of-bounds read error and read the contents of memory on the system.
CVE-2023-42669 2 Redhat, Samba 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Ibm Z Systems and 5 more 2026-06-17 N/A 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-2023-41175 3 Fedoraproject, Libtiff, Redhat 3 Fedora, Libtiff, Enterprise Linux 2026-06-17 N/A 6.5 MEDIUM
A vulnerability was found in libtiff due to multiple potential integer overflows in raw2tiff.c. This flaw allows remote attackers to cause a denial of service or possibly execute an arbitrary code via a crafted tiff image, which triggers a heap-based buffer overflow.
CVE-2023-40745 4 Fedoraproject, Libtiff, Netapp and 1 more 4 Fedora, Libtiff, Active Iq Unified Manager and 1 more 2026-06-17 N/A 6.5 MEDIUM
LibTIFF is vulnerable to an integer overflow. This flaw allows remote attackers to cause a denial of service (application crash) or possibly execute an arbitrary code via a crafted tiff image, which triggers a heap-based buffer overflow.
CVE-2023-40661 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2026-06-17 N/A 5.4 MEDIUM
Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow compromise key generation, certificate loading, and other card management operations during enrollment.
CVE-2023-40660 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2026-06-17 N/A 6.6 MEDIUM
A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.
CVE-2023-40551 2 Fedoraproject, Redhat 3 Fedora, Enterprise Linux, Shim 2026-06-17 N/A 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 3 Fedora, Enterprise Linux, Shim 2026-06-17 N/A 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 3 Fedora, Enterprise Linux, Shim 2026-06-17 N/A 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-2023-40546 2 Fedoraproject, Redhat 3 Fedora, Enterprise Linux, Shim 2026-06-17 N/A 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-2023-3972 1 Redhat 19 Enterprise Linux, Enterprise Linux Aus, Enterprise Linux Desktop and 16 more 2026-06-17 N/A 7.8 HIGH
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
CVE-2023-3971 1 Redhat 5 Ansible Automation Controller, Ansible Automation Platform, Ansible Developer and 2 more 2026-06-17 N/A 7.3 HIGH
An HTML injection flaw was found in Controller in the user interface settings. This flaw allows an attacker to capture credentials by creating a custom login page by injecting HTML, resulting in a complete compromise.
