Debian Security Advisory                                                   Daniel Jacobowitz

Package: xmcd
Vulnerability: untrustworthy privileged binaries
Debian-specific: yes
Vulnerable: yes

The Debian GNU/Linux xmcd package has historically installed two setuid
helpers for accessing cddb databases and SCSI cdrom drives.  More recently,
the package offered the administrator the chance to remove these setuid
flags, but did so incorrectly.

A buffer overflow in ncurses, linked to the "cda" binary, allowed a root
exploit.  Fixed ncurses packages have been released, as well as fixed
xmcd packages which do not install this binary with a setuid flag.

The problem is fixed in xmcd 2.5pl1-7.1, and we recommend all users with
xmcd installed upgrade to this release.  You may need to add users of xmcd
to the "audio" and "cdrom" groups in order for them to continue using xmcd.

Debian GNU/Linux 2.1 alias slink
- --------------------------------

  Slink is no longer being supported by the Debian Security Team.  We highly
  recommend an upgrade to the current stable release.

Debian GNU/Linux 2.2 (stable) alias potato
- ------------------------------------------

  Fixes are currently available for the Alpha, ARM, Intel ia32, Motorola 680x0,
  PowerPC and Sun SPARC architectures, and will be included in 2.2r2.
