GLSA-200410-26 : socat: Format string vulnerability

medium Nessus Plugin ID 15568

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-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 socat.

Solution

All socat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/socat-1.4.0.3'
