Debian Security Advisory
DSA-494-1 ident2 -- buffer overflow
- Date Reported:
- 21 Apr 2004
- Affected Packages:
- ident2
- Vulnerable:
- Yes
- Security database references:
- In the Bugtraq database (at SecurityFocus): BugTraq ID 10192.
In Mitre's CVE dictionary: CVE-2004-0408. - More information:
-
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.
- Fixed in:
-
Debian GNU/Linux 3.0 (woody)
