DESCRIPTION
Samba[1] provides SMB/CIFS services (such as file and printer
sharing) used by clients compatible with Microsoft Windows(TM).
This announcement fixes two denial of service vulnerabilities via
certain malformed requests[2] and via a SAM_UAS_CHANGE request with a
big length value[3] when domain logons are enabled.
It also fixes a problem[4] in the input validation routines used to
convert DOS path names to path names on the Samba host's file system
that could be exploited to gain access to files outside of the
share's path defined by smb.conf.
SOLUTION
It is recommended that all samba users upgrade their packages. This
update will automatically restart the service if it is already
running.
