FreeBSD : glibc -- gethostbyname buffer overflow (0765de84-a6c1-11e4-a0c1-c485083ca99c) (GHOST)

High Nessus Plugin ID 81062


The remote FreeBSD host is missing one or more security-related updates.


Robert Kratky reports :

GHOST is a 'buffer overflow' bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library. This vulnerability allows a remote attacker that is able to make an application call to either of these functions to execute arbitrary code with the permissions of the user running the application. The gethostbyname() function calls are used for DNS resolving, which is a very common event. To exploit this vulnerability, an attacker must trigger a buffer overflow by supplying an invalid hostname argument to an application that performs a DNS resolution.


Update the affected packages.
