Kerentanan Stack-based Buffer Overflow pada redhat 389 directory server. Skor CVSS 3.1 4.9 (Medium) menurut redhat.com.

Deskripsi (NVD)

A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only.
