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.
<impact type="high">
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 &quot;&gt;=net-dialup/capi4k-utils-20050718-r3&quot;</code>
