AI Analysis
Technical Summary
Two vulnerabilities in Red Hat Directory Server's 389-ds-base package affect the SASL authentication handling. CVE-2026-11610 is a heap buffer overflow in the sasl_io_recv() function triggered by a padded SASL UNBIND operation. CVE-2026-11774 is an integer overflow in the SASL packet length that bypasses size limits, also leading to a heap buffer overflow. Both vulnerabilities could potentially lead to memory corruption. Red Hat has issued a security advisory (RHSA-2026:36204) and released updated packages for Red Hat Directory Server 11.5 E4S on RHEL 8.6 to fix these issues.
Potential Impact
Successful exploitation of these vulnerabilities could result in heap buffer overflows, which may lead to application crashes or potentially arbitrary code execution within the context of the directory server process. The advisory rates the security impact as Important (high severity). No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated packages for Red Hat Directory Server 11.5 E4S on RHEL 8.6 that address these vulnerabilities.
