CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE   : icecast
SUMMARY   : Remote buffer overflow vulnerabilities
DATE      : 2001-03-19 11:15:00
ID        : CLA-2001:387
RELEVANT
RELEASES  : 4.1, 4.2, 5.0, 5.1, 6.0

DESCRIPTION
 "icecast" is a server used to distribute audio streams to compatible
 clients such as winamp, mpg123, xmms and many others.
 Matt Messier (mmessier@prilnari.com) and John Viega (viega@list.org)
 have identified several buffer overflow and format strings problems
 in Icecast that could be remotely exploited.
 Our latest update to this software changes the package to use an
 unprivileged user ("icecast") for the daemon, so the impact of this
 vulnerability is not as high. Recent distributions (CL >= 5.1) have
 this package compiled with StackGuard to make it more difficult to
 exploit buffer overflows.


SOLUTION
 All icecast users are urged to upgrade.
