| Doc Text: |
A flaw was found in glibc. When the wordexp function is called with the flags WRDE_REUSE and WRDE_APPEND, it may return uninitialized memory. If the caller inspects the we_wordv array or calls the wordfree function to free the allocated memory, the process will abort, resulting in a denial of service.
