Package: ncurses
Vulnerability: local privilege escalation
Debian-specific: no
Vulnerable: yes

The version of the ncurses display library shipped with Debian GNU/Linux 2.2
is vulnerable to several buffer overflows in the parsing of terminfo
database files.  This problem was discovered by Jouko Pynnönen
<>. The problems are only exploitable in the presence of
setuid binaries linked to ncurses which use these particular functions,
including xmcd versions before 2.5pl1-7.1.

This problem is fixed in ncurses 5.0-6.0potato1 for Debian GNU/Linux 2.2,
and in ncurses 5.0-8 for Debian Unstable.

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.
