A flaw was found in BIND. A remote attacker could exploit this vulnerability by sending a maliciously crafted DNSSEC-validated zone to a BIND resolver. This could cause the resolver to consume excessive CPU resources, leading to a denial of service (DoS) for legitimate users.

Threats
Impact
Important
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.

Threats
Impact
Important
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.

Threats
Impact
Moderate
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.

Threats
Impact
Important
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.

Threats
Impact
Important
A flaw was found in the Linux kernel's traffic control packet editing (pedit) subsystem. In tcf_pedit_act(), the copy-on-write (COW) range for skb_ensure_writable() is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can leave part of the target write region without a proper copy-on-write, leading to an out-of-bounds write that corrupts page cache memory. A local attacker with the ability to configure traffic control rules could exploit this to escalate privileges or crash the system.

An attacker with existing write permissions on the underlying filesystem may manipulate SMB reparse point metadata to alter how files are presented to SMB clients, including converting files into symbolic links.\n\nThe vulnerability does not bypass underlying filesystem access controls or grant additional operating system privileges. However, successful exploitation may significantly disrupt file access for users of the affected share, including making large portions of a shared filesystem unavailable through widespread reparse point modification. Because the attack requires authenticated access and existing filesystem write permissions, Privileges Required are assessed as Low (PR:L).\n\n```\n\nThis vulnerability affects Samba versions beginning with the introduction of NTFS-style reparse point support in Samba 4.21.\n\n```",

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.",

The vulnerable code path is only reachable when Samba Group Policy processing is explicitly enabled using the ```apply group policies = yes``` configuration option and certificate auto-enrollment is configured through Group Policy.\n\nHence, although the vulnerable code is present, it is not exploitable in default RHEL configurations. \n\nIn addition, the attacker must have the ability to intercept or redirect adjacent-network HTTP traffic during certificate retrieval. Because exploitation depends on explicit administrative configuration changes and adjacent-network positioning, Red Hat assesses the attack complexity as High (AC:H).",
