Description
Two heap buffer overflow vulnerabilities were identified in the 389 Directory Server's SASL handling. One involves a heap buffer overflow in sasl_io_recv() triggered by a padded SASL UNBIND (CVE-2026-11610). The other is an integer overflow in SASL packet length that bypasses size limits, leading to a heap buffer overflow (CVE-2026-11774). These issues affect Red Hat Enterprise Linux 9.6 Extended Update Support and related variants. Red Hat has released security updates addressing these vulnerabilities.
