Scientific Linux Security Update : tcpdump on SL5.x i386/x86_64
medium Nessus Plugin ID 60299
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
Problem description :Moritz Jodeit discovered a denial of service bug in the tcpdump IEEE 802.11 processing code. If a certain link type was explicitly specified, an attacker could inject a carefully crafted frame onto the IEEE 802.11 network that could crash a running tcpdump session.
(CVE-2007-1218)
An integer overflow flaw was found in tcpdump's BGP processing code.
An attacker could execute arbitrary code with the privilege of the pcap user by injecting a crafted frame onto the network.
(CVE-2007-3798)
In addition, the following bugs have been addressed :
- The arpwatch service initialization script would exit prematurely, returning an incorrect successful exit status and preventing the status command from running in case networking is not available.
- Tcpdump would not drop root privileges completely when launched with the
- -C option. This might have been abused by an attacker to gain root privileges in case a security problem was found in tcpdump. Users of tcpdump are encouraged to specify meaningful arguments to the -Z option in case they want tcpdump to write files with privileges other than of the pcap user.
Solution
Update the affected arpwatch, libpcap and / or tcpdump packages.See Also
