Asymmetric Resource Consumption vulnerability in…

[CVE catalog]

Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API. A LDAP server using the LDAP API (like Apache DS) may consume 100% of a CPU core indefinitely when processing some badly crafted Telephone Numbers. This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9. Users are recommended to upgrade to version 2.1.9, which fixes the issue.
