DESCRIPTION
 pam_smb is a PAM module that allows applications to authenticate
 against a SMB server (such as Microsoft Windows(TM) or Samba).
 
 A buffer overflow vulnerability has been discovered in the pam_smb
 module. An attacker can execute arbitrary code in the context of the
 program using the module by supplying a long password. Remote root
 access can be gained if remote services such as SSH or FTP are using
 the module (which is not enabled by default in any application
 distributed with Conectiva Linux).
 
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
 assigned the name CAN-2003-0686 to this issue.


SOLUTION
 All pam_smb users should upgrade.
