Debian Security Advisory                                 security@debian.org

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

<jouko@solutions.fi>. 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.
