Greg MacManus discovered an integer overflow in Samba's smbd daemon.
Requesting a very large number of access control descriptors from the
server caused an integer overflow, which resulted in a memory
allocation being too short, thus causing a buffer overflow. By sending
carefully crafted data, an attacker could exploit this to execute

has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected packages.
