FINAL RESULTS:
data/pax-utils-1.2.6/security.c:156:12: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
SCMP_SYS(readlink),
data/pax-utils-1.2.6/dumpelf.c:60:2: [4] (format) printf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
printf( \
data/pax-utils-1.2.6/pspax.c:87:6: [4] (buffer) fscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function.
if (fscanf(fp, "%s.1023", str) != 1) {

data/pax-utils-1.2.6/pspax.c:351:6: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.

easily misused).

if available.

data/pax-utils-1.2.6/scanelf.c:1538:13: [4] (format) snprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
