-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 at 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 '`'.
