Red Hat Security Advisory: redhat-ds:11 security update
Red Hat Directory Server 11.7 for RHEL 8.8 contains two security vulnerabilities involving heap buffer overflows triggered by issues in SASL packet processing. 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). Red Hat has released an important security update addressing these issues.
AI Analysis
Technical Summary
Red Hat Directory Server, an LDAPv3-compliant directory server, was found vulnerable to two heap buffer overflow issues in the 389-ds-base component. The first vulnerability (CVE-2026-11610) occurs in the sasl_io_recv() function triggered by a padded SASL UNBIND message. The second (CVE-2026-11774) involves an integer overflow in the SASL packet length that bypasses size restrictions, leading to a heap buffer overflow. These vulnerabilities could potentially lead to memory corruption. Red Hat has issued an important security advisory (RHSA-2026:36208) providing updated packages for Red Hat Directory Server 11.7 on RHEL 8.8 to remediate these issues.
Potential Impact
The vulnerabilities allow heap buffer overflows in the LDAP server component, which could lead to memory corruption. This may result in denial of service or potentially arbitrary code execution depending on exploitation, though no known exploits in the wild have been reported. The security impact is rated as Important by Red Hat.
Mitigation Recommendations
Red Hat has released updated packages for Red Hat Directory Server 11.7 on RHEL 8.8 that fix these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2026:36208 and the referenced article https://access.redhat.com/articles/11258. No alternative mitigations are indicated; applying the official patch is the recommended remediation.
