The backticks in the arithmetic +epxression are evaluated by in a shell even if WRDE_NOCMD forbade +command substitution. This allows an attacker to attempt to pass +dangerous commands via constructs of the above form, and bypass +the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD +in exec_comm(), the only place that can execute a shell. All other +checks for WRDE_NOCMD are superfluous and removed. + +We expand the testsuite and add 3 new regression tests of roughly +the same form but with a couple of nested levels. + +On top of the 3 new tests we add fork validation to the WRDE_NOCMD +testing. If any forks are detected during the execution of a wordexp() +call with WRDE_NOCMD, the test is marked as failed. This is slightly +heuristic since vfork might be used in the future, but it provides a +higher level of assurance that no shells were executed as part of +command substitution with WRDE_NOCMD in effect. In addition it doesn't +require libpthread or libdl, instead we use the public implementation +namespace function __register_atfork (already part of the public ABI +for libpthread). + +Tested on x86_64 with no regressions. + +(cherry picked from commit a39208bd7fb76c1b01c127b4c61f9bfd915bfe7c) +--- + +diff --git a/posix/wordexp-test.c b/posix/wordexp-test.c +index 4957006..bdd65e4 100644 +--- a/posix/wordexp-test.c ++++ b/posix/wordexp-test.c +@@ -27,6 +27,25 @@ + + #define IFS " \n\t" + ++extern void *__dso_handle __attribute__ ((__weak__, __visibility__ ("hidden"))); ++extern int __register_atfork (void (*) (void), void (*) (void), void (*) (void), void *); ++ ++static int __app_register_atfork (void (*prepare) (void), void (*parent) (void), void (*child) (void)) ++{ ++ return __register_atfork (prepare, parent, child, ++ &__dso_handle == NULL ?
