capi4k-utils is a set of utilities for accessing COMMON-ISDN-API software interfaces for ISDN devices.

The bufprint() function in capi4k-utils fails to properly check boundaries of data coming from CAPI packets.

A local attacker could possibly escalate privileges or cause a Denial of Service by sending a crafted CAPI packet.

There is no known workaround at this time.

All capi4k-utils users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-dialup/capi4k-utils-20050718-r3"
