DESCRIPTION:
A security issue has been reported in Sympa, which can be exploited
by malicious, local users to perform actions with escalated
privileges.

The security issue is caused due to the sympa.pl script creating
files in an insecure manner. This can be exploited via symlink
attacks to modify arbitrary files with the privileges of the user
running the affected script with the "--make_alias_file" option.

The security issue is reported version 5.4.3. Other versions may also
be affected.

SOLUTION:
Fixed in the CVS repository.
