Description
Red Hat Directory Server 12 for RHEL 9.4 contains two security vulnerabilities involving heap buffer overflows triggered by malformed SASL packets. These include a heap buffer overflow in sasl_io_recv() via padded SASL UNBIND (CVE-2026-11610) and an integer overflow in SASL packet length that bypasses size limits leading to a heap buffer overflow (CVE-2026-11774). An update addressing these issues is available.
