Samba is a suite of SMB and CIFS client/server programs.
Samba does not properly check memory boundaries when handling trans, rans2, and nttrans requests.
A remote attacker could send specially crafted requests to a Samba daemon, leading to the disclosure of arbitrary memory or to a Denial of Service.
There is no known workaround at this time.
All Samba users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.33"
