CVE-2023-5868 2 Postgresql, Redhat 22 Postgresql, Advanced Cluster Security, Codeready Linux Builder Eus and 19 more 2026-06-23 4.3 Medium
A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with 'unknown'-type arguments. Handling 'unknown'-type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.
CVE-2026-2340 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-06-23 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-2026-4480 2 Redhat, Samba 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-06-23 9 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 11 Enterprise Linux, Enterprise Linux Eus, Openshift and 8 more 2026-06-23 9 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 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-06-23 8 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-2026-1933 2 Redhat, Samba 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more 2026-06-23 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-2026-9064 1 Redhat 12 389 Directory Server, Directory Server, Directory Server E4s and 9 more 2026-06-18 7.5 High
A flaw was found in 389-ds-base. The get_ldapmessage_controls_ext() function in the LDAP server does not enforce an upper bound on the number of controls per LDAP message. A remote, unauthenticated attacker can send a specially crafted LDAP request containing hundreds of thousands of minimal controls within the default maximum BER message size (2 MB), causing excessive CPU consumption and heap allocation on the server. Under concurrent exploitation, this leads to significant latency degradation, worker thread starvation, or out-of-memory termination, resulting in a denial of service.
CVE-2026-5201 2 Gnome, Redhat 12 Gdk-pixbuf, Ai Inference Server, Enterprise Linux and 9 more 2026-06-10 7.5 High
A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.
CVE-2026-4424 2 Libarchive, Redhat 21 Libarchive, Ai Inference Server, Discovery and 18 more 2026-06-10 7.5 High
A flaw was found in libarchive. This heap out-of-bounds read vulnerability exists in the RAR archive processing logic due to improper validation of the LZSS sliding window size after transitions between compression methods. A remote attacker can exploit this by providing a specially crafted RAR archive, leading to the disclosure of sensitive heap memory information without requiring authentication or user interaction.
CVE-2026-4111 1 Redhat 11 Ai Inference Server, Discovery, Enterprise Linux and 8 more 2026-06-10 7.5 High
A flaw was identified in the RAR5 archive decompression logic of the libarchive library, specifically within the archive_read_data() processing path. When a specially crafted RAR5 archive is processed, the decompression routine may enter a state where internal logic prevents forward progress. This condition results in an infinite loop that continuously consumes CPU resources. Because the archive passes checksum validation and appears structurally valid, affected applications cannot detect the issue before processing. This can allow attackers to cause persistent denial-of-service conditions in services that automatically process archives.
CVE-2023-52356 2 Libtiff, Redhat 6 Libtiff, Ai Inference Server, Discovery and 3 more 2026-06-10 7.5 High
A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, leading to a denial of service.
CVE-2026-5119 2 Gnome, Redhat 9 Libsoup, Enterprise Linux, Enterprise Linux Eus and 6 more 2026-06-09 5.9 Medium
A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation.
