Subject: [PATCH 2/2] libss: fix possible NULL pointer dereferece on allocation
|
||
|
|
failure
|
||
|
|
Content-Type: text/plain
|
||
|
|
|
||
|
|
Currently in ss_execute_command() we're missng a check to see if the
|
||
|
|
memory allocation was succesful. Fix it by checking the return from
|
||
|
|
malloc and returning ENOMEM if it had failed.
|
||
|
|
|
||
|
|
[ Removed addition of the SS_ET_ENOMEM entry to the the libss error
|
||
|
|
table. -TYT ]
