CVE-2026-102731 Apache Directory LDAP API: Denial of service via excessive memory allocation in BER decode
Memory allocation with excessive size value vulnerability in Apache Directory LDAP API. A malicious peer or a MITM can send a small BER-encoded response causing a large memory allocation before any data is received. This can lead to an OutOfMemoryError and denial of service. The client JVM OOMs...
