Memory allocation with excessive size value vulnerability in Apache Directory LDAP API.<\/p>\n
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.<\/p>\n
The client JVM OOMs (OutOfMemoryError bypasses the DecoderException handlers) or pins the large allocation per connection while the attacker stalls.<\/p>\n
A handful of connections exhausts any heap. The same bytes from an unauthenticated pre-bind client hit any embedding server that did not set MAX_PDU_SIZE_ATTR.<\/p>\n
This issue affects Apache Directory LDAP API: from 1.2.0 before 1.2.9.<\/p>\n
Users are recommended to upgrade to version 1.2.9, which fixes the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"
