Background ========== socat is a multipurpose bidirectional relay, similar to netcat. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/socat < 1.4.0.3 >= 1.4.0.3 Description =========== 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. Resolution ========== All socat users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/socat-1.4.0.3" References ========== [ 1 ] socat Security Advisory http://www.dest-unreach.org/socat/advisory/socat-adv-1.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-26.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
