Lifecycle Timeline
3DescriptionNVD
A flaw was found in 389 Directory Server. The LDIF parser reads past the end of a heap buffer when processing attribute types with trailing semicolons during database import, causing an out-of-bounds read detectable under memory instrumentation.
AnalysisAI
Out-of-bounds read in 389 Directory Server's LDIF parser exposes limited heap memory to a highly privileged local attacker during database import operations. Exploitation requires local system access, high attack complexity, and high privileges (administrator-level), producing only minor confidentiality impact with no integrity or availability consequences. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires three simultaneous conditions: (1) local system access (AV:L) - remote network triggering is not possible per the CVSS vector; (2) high privileges (PR:H) - the attacker must hold administrative credentials sufficient to invoke LDIF database import operations, such as root or the 'cn=Directory Manager' account; (3) high attack complexity (AC:H) - the specific LDIF input must include attribute types with trailing semicolons and may require additional conditions to produce a meaningful read. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The compound signal picture here is unambiguous: this is a genuinely low-risk finding. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A system administrator or a threat actor who has already achieved root or directory-admin privileges on a Red Hat Enterprise Linux host crafts a malformed LDIF file containing attribute type descriptors with trailing semicolons, then initiates a database import operation against the 389 Directory Server instance. The LDIF parser reads past the end of a heap buffer, potentially exposing a small amount of adjacent heap memory. … |
| Remediation | No vendor-released patch version is independently confirmed from the available source data; monitor https://access.redhat.com/security/cve/CVE-2026-11786 and https://bugzilla.redhat.com/show_bug.cgi?id=2485426 for fix availability and errata releases. … Detailed patch versions, workarounds, and compensating controls in full report. |
