[Issue 7439] crash in rwm when tree is syncrepl synced and database ldap with rwm inside same tree
by openldap-its＠openldap.org 19 Jan '21

19 Jan '21

https://bugs.openldap.org/show_bug.cgi?id=7439 --- Comment #5 from Ondřej Kuzník <ondra(a)mistotebe.net> --- (In reply to Howard Chu from comment #4) > Right, rwm should probably stash the incoming filter and restore it on > return. The overlay seems quite confused in what it wants to do, parts of it want to maintain the original filter as is (rwm_callback_get, rwm_op_rollback) while parts are very intrusive (rwm_int_filter_map_rewrite). I'll see if I can change how rwm_int_filter_map_rewrite mangles the op/its filter. -- You are receiving this mail because: You are on the CC list for the issue.

[Issue 9420] New: memory leak & ub in servers/slapd/modrdn.c`slap_modrdn2mods()
by openldap-its＠openldap.org 18 Jan '21

18 Jan '21

https://bugs.openldap.org/show_bug.cgi?id=9420 Issue ID: 9420 Summary: memory leak & ub in servers/slapd/modrdn.c`slap_modrdn2mods() Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: slapd Assignee: bugs(a)openldap.org Reporter: grapvar(a)gmail.com Target Milestone: --- Created attachment 781 --> https://bugs.openldap.org/attachment.cgi?id=781&action=edit fix Hi. I have noticed 1) a memory leak in failure cleanup section of slap_modrdn2mods(): | for ( ; op->orr_modlist != NULL; op->orr_modlist = tmp ) { | tmp = op->orr_modlist->sml_next; | ch_free( op->orr_modlist ); | } this code leaks (n)values of mods. And 2) undefined behavior while scheduling delete: | (void) (*desc->ad_type->sat_equality->smr_normalize)(..., &mod_tmp->sml_nvalues[0], ...) this code doesn't respect normalization failures, and may leave garbage in nvalues[0]. I guess this is because somebody assumed normalization can't fail here, because the value has already been normalized during dnPrettyNormal. But ... normalization can fail at least because some normalizators do not abort() on memory allocation failures. Here is a patch that fixes these defects. Please, consider. -- You are receiving this mail because: You are on the CC list for the issue.
