Description

Background

Net::Server is an extensible, generic Perl server engine. It is used by several Perl applications like Postgrey.

Description

The log function of Net::Server does not handle format string specifiers properly before they are sent to syslog.

Impact

By sending a specially crafted datastream to an application using Net::Server, an attacker could cause a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Net::Server should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-perl/net-server-0.88"
