------------------------------------------------------------------------ Debian Security Advisory DSA-070-1 security@debian.org Debian -- Security Information Robert van der Meulen August 10, 2001 ------------------------------------------------------------------------ Package : netkit-telnet Problem type : remote exploit Debian-specific: no The telnet daemon contained in the netkit-telnet_0.16-4potato1 package in the 'stable' (potato) distribution of Debian GNU/Linux is vulnerable to an exploitable overflow in its output handling. The original bug was found by <scut@nb.in-berlin.de>, and announced to bugtraq on Jul 18 2001. At that time, netkit-telnet versions after 0.14 were not believed to be vulnerable. On Aug 10 2001, zen-parse posted an advisory based on the same problem, for all netkit-telnet versions below 0.17. More details can be found on . As Debian uses the 'telnetd' user to run in.telnetd, this is not a remote root compromise on Debian systems; the 'telnetd' user can be compromised. We strongly advise you update your netkit-telnet packages to the versions listed below. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. Debian GNU/Linux 2.2 alias potato --------------------------------- Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
