[RHEL4] [patch] cid-21 Fix memory leak in libss (ss_execute_line)
Last modified: 2015-01-07 19:15:37 EST
Description of problem:
The function ss_execute_line in execute_cmd.c contains the following code:
/* parse it */
argv = ss_parse(sci_idx, line_ptr, &argc);
if (argc == 0)
Potentially we need to free argv before early return since it was allocated
memory. We need to be careful and check argv since it may be possible for
ss_parse() to have freed the memory allocated to it if it detects an unbalanced
set of quotes passed to it.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Also tricky to reproduce this one. I'm not familiar with ss's internals to come
up with a test case that will clearly show this problem, but again the flaw is
ss_execute_line may fail to free resources allocated by it.
ss_execute_line correctly frees resources allocated by it.
