Debian: New libpam-smb packages fix buffer overflow

libpam-smb is a PAM authentication module which makes it possible to authenticate users against a password database managed by Samba or a Microsoft Windows server. If a long password is supplied, this can cause a buffer overflow which could be exploited to execute arbitrary code with the privileges of the process which invokes PAM services. Fixed packages are available from security.debian.org.
