pine.nl> Issue date : 2002-06-25 Application : Multiple Version(s) : Multiple Platforms : FreeBSD, OpenBSD, NetBSD, maybe more. Availability : http://www.pine.nl/advisories/pine-cert-20020601.txt -----------------------------------------------------------------------------
Synopsis
There is a remote buffer overflow in the resolver code of libc.
Impact
Serious.
Exploitability will vary on application-specific issues.
Description
There is a slight mistake in the resolver code of libc.
This will allow an attacker-controlled DNS server to reply with a carefully crafted message to (for example) a gethostbyname request. This reply will trigger the buffer overflow
Solution
FreeBSD, NetBSD and OpenBSD CVS have been updated. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (SunOS)
