CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to improper handling of Lightweight Directory Access Protocol (LDAP) search filters by the 389-ds-base package. A remote attacker can send a specially crafted LDAP request, trigger a stack-based buffer overflow condition and cause the ns-slapd process to crash.
Successful exploitation of the vulnerability results in denial of service.
