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.
