Mandrake Linux Security Advisory : tcpdump (MDKSA-2002:032)
High Nessus Plugin ID 13938
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionSeveral buffer overflows were found in the tcpdump package by FreeBSD developers during a code audit, in versions prior to 3.5. However, newer versions of tcpdump, including 3.6.2, are also vulnerable to another buffer overflow in the AFS RPC decoding functions, which was discovered by Nick Cleaton. These vulnerabilities could be used by a remote attacker to crash the the tcpdump process or possibly even be exploited to execute arbitrary code as the user running tcpdump, which is usually root.
The newer libpcap 0.6 has also been audited to make it more safe by implementing better buffer boundary checks in several functions.
SolutionUpdate the affected packages.
