Full_Name: Matthew Backes Version: 2.4, HEAD OS: any URL: Submission from: (NULL) (76.88.107.46) The lockobj's in BDB aren't being DBTzero()'d fully before use; they consist of more than just .data and .size, so this leaves uninit memory that gets branched on. Needs to be applied to HEAD and 2.4. (2.3 as well, for those still tracking that for some reason, probably all branches with BDB/HDB) Patch vs HEAD: =================================================================== RCS file: /repo/OpenLDAP/pkg/ldap/servers/slapd/back-bdb/cache.c,v retrieving revision 1.214 diff -u -u -r1.214 cache.c --- cache.c 4 Nov 2009 05:09:51 -0000 1.214 +++ cache.c 29 Mar 2010 16:41:59 -0000 @@ -184,6 +184,7 @@ if ( !lock ) return 0; + DBTzero( &lockobj ); lockobj.data = &ei->bei_id; lockobj.size = sizeof(ei->bei_id) + 1; @@ -225,6 +226,7 @@ else db_rw = DB_LOCK_READ; + DBTzero( &lockobj ); lockobj.data = &ei->bei_id; lockobj.size = sizeof(ei->bei_id) + 1; Index: dn2id.c =================================================================== RCS file: /repo/OpenLDAP/pkg/ldap/servers/slapd/back-bdb/dn2id.c,v retrieving revision 1.169 diff -u -u -r1.169 dn2id.c --- dn2id.c 15 Feb 2010 14:25:47 -0000 1.169 +++ dn2id.c 29 Mar 2010 16:41:59 -0000 @@ -42,6 +42,7 @@ else db_rw = DB_LOCK_READ; + DBTzero( &lockobj ); lockobj.data = dn->bv_val; lockobj.size = dn->bv_len;
