Title:	Conectiva Security Advisory CLA-2002:480
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory CLA-2002:480. Tcpdump is a command-line tool for monitoring network traffic. It uses libpcap, a library which provides a portable framework for low-level network monitoring. Both are developed by the same team[1]. This advisory addresses problems found in both projects. tcpdump buffer overflows: during a tcpdump code auditing done by FreeBSD developers, several buffer overflows were discovered[2] in tcpdump versions prior to 3.5. New versions (including 3.6.2) are also vulnerable to another buffer overflow[3] in AFS RPC decoding functions, as pointed out by Nick Cleaton . These vulnerablities could be exploited by a remote attacker to crash the tcpdump process or even execute arbitrary code as the user running tcpdump (which usually is root). libpcap 0.6 has been audited and a better buffer boundary checking was implemented in several functions, thus making it more safe. This upgrade also fixes a lot of minor bugs[4] in both tcpdump and libpcap. Notice that the number of vulnerabilities and bug fixes which apply to every version of Conectiva Linux varies accordingly to the tcpdump/libpcap versions included in it. This update brings all packages to the most recent version as of this date plus the tcpdump security patches which have not yet been included in the upstream stable version (3.6.2). Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.tcpdump.org/ http://www.ciac.org/ciac/bulletins/l-015.shtml http://www.tcpdump.org/tcpdump-changes.txt http://www.securityspace.com/smysecure/catid.html?in=CLA-2002:480 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002002 Risk factor : High
