WARNING !!! WARNING !!! WARNING !!! WARNING !!! WARNING !!! -EMBARGOED !!! EMBARGOED !!! EMARGOED !!! EMBARGOED !!! EMBARGOED !!! -SECURITY !!! SECURITY !!! SECURITY !!! SECURITY !!! SECURITY !!! - -CVE-2014-7817: - -The function wordexp() fails to properly handle the WRDE_NOCMD -flag when processing arithmetic inputs in the form of "$((... ``))" -where "..." can be anything valid. 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 parse_arith(). The patch also hardens parse_backticks() and -parse_comm() to check for WRDE_NOCMD flag and return an error instead -of ever running a shell. - -We expand the testsuite and add 3 new regression tests of roughtly -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, 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. - -2014-10-27 Carlos O'Donell <carlos@redhat.com> - - * wordexp-test.c (__dso_handle): Add prototype. - (__register_atfork): Likewise. - (__app_register_atfork): New function. - (registered_forks): New global. - (register_fork): New function. - (test_case): Add 3 new tests for WRDE_CMDSUB. - (main): Call __app_register_atfork. - (testit): If WRDE_NOCMD set registered_forks to zero, run test, and - if fork count is non-zero fail the test. - * posix/wordexp.c (parse_arith): Return WRDE_NOCMD if WRDE_NOCMD flag - is set and parsing '`'. - (parse_comm): Return WRDE_NOCMD if WRDE_NOCMD flag is set. - (parse_backtick): Return WRDE_NOCMD if WRDE_NOCMD flag is set and - parsing '`'. - -diff --git a/posix/wordexp-test.c b/posix/wordexp-test.c -index 4957006..5ce2a1b 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 ?
