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.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/tcpdump-3.9.5-r3'
