medium Nessus Plugin ID 25810

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200707-14 (tcpdump: Integer overflow)

mu-b from Digital Labs discovered that the return value of a snprintf() call is not properly checked before being used. This could lead to an integer overflow.
Impact :

A remote attacker could send specially crafted BGP packets on a network being monitored with tcpdump, possibly resulting in the execution of arbitrary code with the privileges of the user running tcpdump, which is usually root.
Workaround :

There is no known workaround at this time.

Solution

All tcpdump users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/tcpdump-3.9.5-r3'
