Description
Two security vulnerabilities have been identified in the 389 Directory Server (389-ds-base) used in Red Hat Enterprise Linux 9. These include a heap buffer overflow triggered via padded SASL UNBIND messages (CVE-2026-11610) and an integer overflow in SASL packet length that bypasses size limits, also leading to a heap buffer overflow (CVE-2026-11774). Both flaws could potentially allow attackers to cause memory corruption. Red Hat has released security updates addressing these issues for multiple architectures and variants of Red Hat Enterprise Linux 9.
