Summary

Red Hat Security Advisory: Red Hat Directory Server security and bug fix update

Severity

Low

Notes

Topic: Updated Red Hat Directory Server and related packages that fix one security issue and multiple bugs are now available for Red Hat Directory Server 8.2. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Details: The redhat-ds-base packages provide Red Hat Directory Server, which is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration. A flaw was found in the way the 389 Directory Server daemon (ns-slapd) handled access control instructions (ACIs) using certificate groups. If an LDAP user that had a certificate group defined attempted to bind to the directory server, it would cause ns-slapd to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2012-0833) Red Hat would like to thank Graham Leggett for reporting this issue. This update also fixes the following bugs: * Search with a complex filter that included a range search filter was slow. (BZ#853004) * If the server was restarted, or there was some type of connection failure, it was possible that users were no longer able to log into the console. Manual action is required to apply this fix: You must add an aci to each "cn=Server Group" entry in "o=netscaperoot", that allows anonymous/all users read/search rights. (BZ#856089) * With replication enabled, trying to replace an existing value, where the new value only differs in case (for example, changing "cn: foo" to "cn: FOO"), resulted in the operation failing with an error 20. (BZ#891866) All users of Red Hat Directory Server 8.2 should upgrade to these updated packages, which resolve these issues.

CVE-2012-0833 (GCVE-0-2012-0833)

Vulnerability from cvelistv5 – Published: 2012-07-03 16:00 – Updated: 2024-08-06 18:38

Summary

The acllas__handle_group_entry function in servers/plugins/acl/acllas.c in 389 Directory Server before 1.2.10 does not properly handled access control instructions (ACIs) that use certificate groups, which allows remote authenticated LDAP users with a certificate group to cause a denial of service (infinite loop and CPU consumption) by binding to the server.

Severity

No CVSS data available.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
