Subject: Fix memory leak in read_header
|
||||
|
||||
https://git.savannah.gnu.org/cgit/tar.git/commit/?id=d9d4435692150fa8ff68e1b1a473d187cc3fd777
|
||||
|
||||
Bug reported in https://savannah.gnu.org/bugs/?59897
|
||||
|
||||
* src/list.c (read_header): Don't return directly from the loop.
|
||||
Instead set the status and break. Return the status. Free
|
||||
next_long_name and next_long_link before returning.
