|Gentoo Linux Security Advisory
Title: capi4k-utils: Buffer overflow (GLSA 200704-23)
Date: April 27, 2007
capi4k-utils is vulnerable to a buffer overflow in the bufprint() function.
capi4k-utils is a set of utilities for accessing COMMON-ISDN-API software interfaces for ISDN devices.
Vulnerable: < 20050718-r3
Unaffected: >= 20050718-r3
Architectures: All supported architectures
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"
