Subject: [PATCH] Fix double-free in _cl5NewDBFile() error path
|
|
|
74ca47 |
|
|
|
74ca47 |
Although slapi_ch_free should prevent double-free errors, it doesn't work
|
|
|
74ca47 |
in old code because after assignment
|
|
|
74ca47 |
|
|
|
74ca47 |
(*dbFile)->name = name;
|
|
|
74ca47 |
|
|
|
74ca47 |
two independent pointers points to the same allocated area and both pointers
|
|
|
74ca47 |
are free()-ed (one directly in error path in _cl5NewDBFile and the second
|
|
|
74ca47 |
in _cl5DBCloseFile, called in error path as well).
