Any clues here are greatly appreciated. Appears to be a bug in gentoo's build rules for this plugin. The OpenLDAP Project doesn't supply build rules for this plugin, so there's nothing for us to fix here. Closing this ITS. Note that the function of this particular plugin was superseded long ago, there's no reason to even build it. > PS: This is a Gentoo Prefix set up I am working with. > > https://bugs.gentoo.org/show_bug.cgi?id=536306 > > -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Full_Name: Rohan Kurane Version: 2.4.40 OS: BSD 7.2 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (64.80.217.3) In ldap_new_connection() in request.c, while setting up a connection to the LDAP server, there is a possibility of dereferencing a NULL pointer in lc->locnn_server if ( connect ) { LDAPURLDesc **srvp, *srv = NULL; async % LDADAP_BOOL_GET( &ld->ld_options, LDAP_BOOL_CONNECT_ASYNC ); for ( srvp = srvlist; *srvp != NULL; srvp = &(*srvp)->lud_next ) { int rc; rc = ldap_int_open_connection( ld, lc, *srvp, async ); if ( rc != -1 ) { srv = *srvp; 9%9 if ( ld->ld_urllist_proc && ( !async || rc != -2 ) ) { ld->ld_urllist_proc( ld, srvlist, srvp, ld->ld_urllist_params ); } break; } } if ( srv == NULL ) { if ( !use_ldsb ) { ber_sockbuf_free( lc->lconn_sb ); %%D LDAP_FREE( (char *)lc ); ld->ld_errno = LDAP_SERVER_DOWN; return( NULL ); } lc->lconn_server = ldap_url_dup( srv ); } ldap_url_dup() does a bunch of malloc's to set up lc->lconn_server. If any of those malloc's fail, it returns NULL. The code does not check for a NULL lconn_server pointer and tries to reference lud_exts. That can cause a segmentation fault. if ( connect ) { #ifdef HAVE_TLS if ( lc->lconn_server->lud_exts ) { int rc, ext = find_tls_ext( lc->lconn_server ); if ( ext ) { LDAPConn *savedefconn; Even thou this should not happen, is this a known issue and are there any plans to fix the openldap library ?

But it is also too late, we must get rid of any garbage value in md_pid at once to protect it from other processes' env_close(). Fixing. Also, I'll rename the confusingly named me_numreaders to me_close_readers and drop some confused code using it.
