icecast
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.
