Description

This security bulletin contains information about 3 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2026-58216)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to cause a denial of service.

The vulnerability exists due to an out-of-bounds read in the KDC kpasswd packet ASN.1 parsing when processing a malformed kpasswd packet. A remote user can send a specially crafted kpasswd packet to cause a denial of service.

The invalid access is limited to 6 bytes of unallocated memory, and the accessed memory is not exposed to the user.


2) Resource exhaustion (CVE-ID: CVE-2026-58218)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource management in the DNS TKEY name cache when repeatedly registering TKEY names. A remote attacker can repeatedly register names to cause a denial of service.

The issue can flood the cache and expunge legitimate TKEYs, practically blocking DNS TSIG signing.


3) SQL injection (CVE-ID: CVE-2026-58222)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to filter injection and trusted-request confusion in the LDAP Compare operation when handling LDAP Compare requests. A remote user can send crafted LDAP Compare requests to disclose sensitive information.

Confidential Active Directory attributes, including KDS root keys, can be queried by bypassing access checks.
