Description

It has been discovered that the last security update for Samba, a LanManager like file and printer server for GNU/Linux and Unix-like systems caused the daemon to crash upon reload. This has been fixed. For reference below is the original advisory text :

Greg MacManus discovered an integer overflow in the smb daemon from Samba, a LanManager like file and printer server for GNU/Linux and Unix-like systems. Requesting a very large number of access control descriptors from the server could exploit the integer overflow, which may result in a buffer overflow which could lead to the execution of arbitrary code with root privileges. Upstream developers have discovered more possible integer overflows that are fixed with this update as well.
