Description Laura Pardo 2018-01-22 22:28:49 UTC
A flaw was found in 389 Directory Server, affecting all versions including upstream 1.4.x. An improper handling of the search feature with an extended filter, when read access on <attribute_name> is enabled, in SetUnicodeStringFromUTF_8 function in collate.c, can lead to out-of-bounds memory operations. This may allow a remote unauthenticated attacker to trigger a server crash, thus resulting in denial of service.
