e0761b9e3b Also free safe_cmnd so it doesn't leak. 2021-02-22 20:18:49 -07:00
Todd C. Miller
322e0b3693 Return NOT_FOUND from the set_cmnd_path() stub since we don't set user_cmnd. 
The purpose of set_cmnd_path() is to reset user_cmnd based on a new
runchroot.  For the stub version we don't modify user_cmnd and so
must not return a status of FOUND.
Fixes oss-fuzz issue #31250 which only affected the fuzzer and not sudo.

df42c0c1d2 Perform matching in fuzz_sudoers for inputs that parse correctly. 
The fuzzer now exercised the normal match code as well as the
pseudo-command (list, validate, etc) match code.

387169ac67 Add support on AIX for loading plugins that are .a (not .so) files. 
It is possible to specify the member name in parens after the path,
e.g. sudoers.a(shr.o) for 32-bit or sudoers.a(shr_64.o) for 64-bit.
If no member is specified in the path and dlopen() fails with ENOEXEC,
try again with an explicit member, either shr.o or shr_64.o.
