A flaw was found in 389 Directory Server. The Content Synchronization persistent search plugin allows unbounded memory growth when an authenticated client stops reading sync responses, enabling denial of service. Additional race conditions in plugin thread lifecycle can cause crashes during connection teardown or shutdown.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:3137-1 advisory.

    Update to version 2.2.10~git255.752643c78.

    Security issues fixed:

    - CVE-2026-11610: missing bounds check in `sasl_io_recv()` can lead to a heap buffer overflow when     processing a       specially crafted oversized LDAP UNBIND packet (bsc#1270695).
    - CVE-2026-11611: Content Synchronization persistent search plugin allows unbounded memory growth when an     authenticated       client stops reading sync responses(bsc#1267975).
    - CVE-2026-11774: integer overflow in `sasl_io_start_packet()` can lead to heap buffer overflow when     processing a       crafted SASL packet length prefix (bsc#1268298).
    - CVE-2026-11785: type confusion in the SSO token handler can cause partial stack address information     disclosure in       LDA responses (bsc#1268065).
    - CVE-2026-11786: out-of-bounds read in the LDIF parser when processing attribute types with trailing     semicolons during       database import (bsc#1268064).
    - CVE-2026-11787: missing bounds check in the `ldap_utf8prev()` functioncan can lead to a heap buffer     overread in       string filter parsing(bsc#1268062).
    - CVE-2026-11788: missing allocation check in the dereference control plugin  before using a BER structure     can lead to       LDAP server crash when the system is under memory pressure (bsc#1268057).
    - CVE-2026-11789: integer underflow in the SMD5 password storage plugin can lead to a buffer overread when     computing       salt length from a crafted password hash shorter than 16 bytes (bsc#1268058).
    - CVE-2026-11790: improper bounds enforcement in the BKDF2-SHA256 password storage plugin can lead to     excessive       resource consumption during authentication and cause a DoS (bsc#1268060).
    - CVE-2026-11791: use-after-free in the schema reload mechanism can lead to a `ns-slapd` crash when     concurrent LDAP       query traffic is active (bsc#1268047).
    - CVE-2026-11792: missing checks in `create_masked_entry_string` can lead to a heap and log output     corruption whe a       short cleartext password is logged  (bsc#1268046).
    - CVE-2026-11793: missing bounds check in `checkPrefix()` can lead to a stack buffer overflow when     processing an       algorithm ID during parsing of reversible-encrypted attribute values (bsc#1268041).
    - CVE-2026-11884: improper string management can lead to heap buffer overflow when serializing objectclass     definitions       (bsc#1268115).
    - CVE-2026-12528: missing length checks in the `__aclp__normalize_acltxt()` function can lead to heap     buffer overflow       when processing a malformed ACI string (bsc#1268491).
