GLSA-200404-03 : Tcpdump Vulnerabilities in ISAKMP Parsing

High Nessus Plugin ID 14468


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200404-03 (Tcpdump Vulnerabilities in ISAKMP Parsing)

There are two specific vulnerabilities in tcpdump, outlined in [ reference 1 ]. In the first scenario, an attacker may send a specially crafted ISAKMP Delete packet which causes tcpdump to read past the end of its buffer. In the second scenario, an attacker may send an ISAKMP packet with the wrong payload length, again causing tcpdump to read past the end of a buffer.
Impact :

Remote attackers could potentially cause tcpdump to crash or execute arbitrary code as the 'pcap' user.
Workaround :

There is no known workaround at this time. All tcpdump users are encouraged to upgrade to the latest available version.


All tcpdump users should upgrade to the latest available version.
ADDITIONALLY, the net-libs/libpcap package should be upgraded.
# emerge sync # emerge -pv '>=net-libs/libpcap-0.8.3-r1' '>=net-analyzer/tcpdump-3.8.3-r1' # emerge '>=net-libs/libpcap-0.8.3-r1' '>=net-analyzer/tcpdump-3.8.3-r1'
