CVE-2014-6040
Crashes on invalid input in IBM gconv modules [BZ #17325] These changes are based on the fix for BZ #14134 in commit 6e230d11837f3ae7b375ea69d7905f0d18eb79e5.
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 exec_comm(), the only place that can execute a shell. All other checks for WRDE_NOCMD are superfluous and removed.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
