| CVE-2026-4480 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-15 | N/A | 9.0 CRITICAL |
| A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the "print command" setting via the "%J" substitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system. | |||||
| CVE-2026-4408 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-15 | N/A | 9.0 CRITICAL |
| A flaw was found in Samba. A remote attacker can exploit a misconfiguration in Samba file servers and classic domain controllers that use the "check password script" feature. If this script is configured with the %u substitution character, the client-controlled username is passed without proper escaping of shell meta-characters. This vulnerability allows an attacker to achieve remote command execution on the affected system. This issue primarily affects non-standard configurations where the "check password script" is used with %u and the samba-dcerpcd service is started as a system service. | |||||
| CVE-2026-3012 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-15 | N/A | 8.0 HIGH |
| A flaw was found in Samba’s certificate auto-enrollment Group Policy handling. When certificate auto-enrollment is enabled, Samba may retrieve a CA certificate over an unencrypted HTTP connection and install it into the local trust store without proper verification. An attacker with the ability to intercept or redirect network traffic could exploit this behavior to supply a malicious certificate authority certificate, potentially allowing interception or spoofing of trusted communications. | |||||
| CVE-2026-2340 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-15 | N/A | 6.5 MEDIUM |
| A flaw was found in Samba’s vfs_worm module. The module is intended to provide write-once, read-many (WORM) protections by preventing modification of files after a configurable grace period. Due to insufficient validation during rename operations, an authenticated user with write access to a share could overwrite a protected file by renaming a newly created file over the existing WORM-protected file. | |||||
| CVE-2026-1933 | 2 Redhat, Samba | 3 Enterprise Linux, Openshift Container Platform, Samba | 2026-06-15 | N/A | 7.1 HIGH |
| A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible file behavior, including converting files into symbolic links or other reparse point types. | |||||
| CVE-2026-11611 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-06-15 | N/A | 6.5 MEDIUM |

| A use-after-free flaw was found in the X.Org X server and Xwayland in SyncChangeCounter(). A client that sets up multiple SyncCounters can trigger a use-after-free when destroying those counters via a second client connection while changing those counters. This may be used to crash the server, or for privilege escalation if the X server runs as root. | |||||
| CVE-2026-50262 | 2 Redhat, X.org | 3 Enterprise Linux, X Server, Xwayland | 2026-06-15 | N/A | 5.5 MEDIUM |
| An out-of-bounds read flaw was found in the X.Org X server and Xwayland in __glXDisp_ChangeDrawableAttributes(). A wrong size validation check can read a client-controlled number of bytes, exceeding the request buffer, leading to information disclosure. A write path also exists but requires byte-swapped clients which is disabled by default. | |||||
| CVE-2026-4887 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-06-15 | N/A | 6.1 MEDIUM |
| A flaw was found in GIMP. This issue is a heap buffer over-read in GIMP PCX file loader due to an off-by-one error. A remote attacker could exploit this by convincing a user to open a specially crafted PCX image. Successful exploitation could lead to out-of-bounds memory disclosure and a possible application crash, resulting in a Denial of Service (DoS). | |||||
| CVE-2026-4775 | 3 Debian, Libtiff, Redhat | 4 Debian Linux, Libtiff, Enterprise Linux and 1 more | 2026-06-15 | N/A | 7.8 HIGH |
| A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution. | |||||
