Subject: [PATCH 2/2] Bug 1725845: slapi-nis crashes when returning an entry
|
|
|
9c7f46 |
with invalid DN
|
|
|
9c7f46 |
|
|
|
9c7f46 |
Bug Description:
|
|
|
9c7f46 |
On a search on compat tree, slapi-nis prepared the set of entries to return.
|
|
|
9c7f46 |
It stores the entries into a hashtable, using the normalized DN as a key.
|
|
|
9c7f46 |
If the entry contains an invalid DN, the key is invalid and triggers
|
|
|
9c7f46 |
a crash while adding the entry in the hashtable
