CyberRota Analysis
AI-GeneratedA stack buffer overflow vulnerability exists in the 389 Directory Server, specifically in the get_ruvelement_from_berval() function, which improperly handles network-supplied data, allowing a remote unauthenticated attacker to crash the LDAP server by sending a specially crafted replication request. While stack protection mechanisms may mitigate the impact, this flaw poses a significant denial-of-service risk. Organizations using 389 Directory Server should prioritize patching this vulnerability to maintain service availability and security.
Original NVD Description
A stack buffer overflow flaw was found in 389 Directory Server (389-ds-base). The get_ruvelement_from_berval() function in repl5_ruv.c copies digit characters from a network-supplied RUV berval into a fixed 16-byte stack buffer without bounds checking. A remote unauthenticated attacker can crash the LDAP server by sending a crafted StartNSDS50ReplicationRequest extended operation containing a replica ID field with more than 16 digit characters. The overflow occurs during payload decoding, before any authorization check. Stack protectors limit impact to denial of service.
