Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200410-26
(socat: Format string vulnerability)

socat contains a syslog() based format string vulnerablility in the
'_msg()' function of 'error.c'. Exploitation of this bug is only
possible when socat is run with the '-ly' option, causing it to log
messages to syslog.

Impact :

Remote exploitation is possible when socat is used as a HTTP proxy
client and connects to a malicious server. Local privilege escalation
can be achieved when socat listens on a UNIX domain socket. Potential
execution of arbitrary code with the privileges of the socat process is
possible with both local and remote exploitations.

Workaround :

Disable logging to syslog by not using the '-ly' option when starting

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/socat-'
