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"
