The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1789654818 advisory.

  - A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In     sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper     bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed     encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is     then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer     overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF >     0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code     execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow.
    (CVE-2026-18355)

  - A flaw was found in 389 Directory Server. A missing NULL pointer check in the paged results handling of     op_shared_search allows an unauthenticated remote attacker to crash the LDAP server by sending a crafted     sequence of search requests using the USE_ONE_BACKEND control, resulting in denial of service.
    (CVE-2026-18453)

  - A flaw was found in 389 Directory Server. During SASL PLAIN authentication, a stale identity carried in a     Cyrus SASL auxiliary property from a prior failed bind attempt can be installed on a connection following     a subsequent, unrelated successful bind, regardless of which SASL mechanism completes that second bind. An     attacker can send a SASL PLAIN bind as cn=Directory Manager with an incorrect password, then complete a     SASL ANONYMOUS bind on the same connection, causing the server to grant Directory Manager authority     without any valid credentials. A variant using a valid low-privileged account's own successful bind     instead of an anonymous one is also possible. (CVE-2026-18922)

  - A flaw was found in 389 Directory Server. The SELFDN ACI bind-rule evaluator incorrectly matches an     anonymous LDAP client's empty bind DN against an empty stored attribute value, allowing an unauthenticated     client to satisfy access control checks intended to require a matching authenticated identity. This can     allow an anonymous LDAP client to perform an operation, such as adding or modifying a directory entry,     that a SELFDN-based ACI intended to restrict to a specific authenticated user. (CVE-2026-76560)

  - A flaw was found in 389-ds-base. A remote, authenticated attacker could exploit a vulnerability in the     Simple Authentication and Security Layer (SASL) UNBIND process. By sending a specially crafted request,     the attacker can cause a connection to stall, leading to resource exhaustion and a Denial of Service (DoS)     for the server. (CVE-2026-78701)
