CVE-2017-15134

A stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 handled certain LDAP search filters. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

• CVE-2017-15134: Fixed a remote denial of service via search filters in slapi_filter_sprintf in slapd/util.c (bsc#1076530)
• CVE-2017-15135: Fixed authentication bypass due to lack of size check in slapi_ct_memcmp function in ch_malloc.c (bsc#1076530)
• CVE-2018-10935: Fixed an issue that allowed users to cause a crash via ldapsearch with server side sorts (bsc#1105606)
• CVE-2018-14624: The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(), allowing an attacker to send a flood of modifications to a very large DN, which could have caused slapd to crash (bsc#1106699).
