Two vulnerabilities have been identified in the version of
ldap-account-manager shipped with Debian 3.1 (sarge).

CVE-2006-7191
An untrusted PATH vulnerability could allow a local attacker to execute
arbitrary code with elevated privileges by providing a malicious rm
executable and specifying a PATH environment variable referencing this
executable.

CVE-2007-1840
Improper escaping of HTML content could allow an attacker to execute a
cross-site scripting attack (XSS) and execute arbitrary code in the
victim's browser in the security context of the affected web site.

For the old stable distribution (sarge), this problem has been fixed in
version 0.4.9-2sarge1.  Newer versions of Debian (etch, lenny, and sid),
are not affected.

We recommend that you upgrade your ldap-account-manager package.

sources.list as given below:

apt-get update
        will update the internal database
