-------------------------------------------------------------------------- Debian Security Advisory DSA 494-1 security@debian.org http://www.debian.org/security/ Matt Zimmerman April 21st, 2004 http://www.debian.org/security/faq --------------------------------------------------------------------------
Package : ident2 Vulnerability : buffer overflow Problem-Type : remote Debian-specific: no CVE Ids : CAN-2004-0408
Jack <jack@rapturesecurity.org> discovered a buffer overflow in ident2, an implementation of the ident protocol (RFC1413), where a buffer in the child_service function was slightly too small to hold all of the data which could be written into it. This vulnerability could be exploited by a remote attacker to execute arbitrary code with the privileges of the ident2 daemon (by default, the "identd" user).
For the current stable distribution (woody) this problem has been fixed in version 1.03-3woody1.
For the unstable distribution (sid), this problem will be fixed soon.
We recommend that you update your ident2 package.
Upgrade Instructions --------------------
wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
If you are using the apt-get package manager, use the line for sources.list as given below:
apt-get update will update the internal database apt-get upgrade will install corrected packages
