An out-of-bounds write flaw was found in the way the glibc’s readdir_r() function handled file system entries longer than the NAME_MAX character constant. A remote attacker could provide a specially crafted NTFS or CIFS file system that, when processed by an application using readdir_r(), would cause that application to crash or, potentially, allow the attacker to execute arbitrary code with the privileges of the user running the application. (CVE-2013-4237)
It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. (CVE-2013-4458)
