medium Nessus Plugin ID 328689

Synopsis

The remote SUSE host is missing one or more security updates.

Description

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).
