TITLE

router advertisement daemon In radvd The daemon root Vulnerabilities run as

DESCRIPTION

The router advertisement daemon (radvd) before 1.8.2 does not properly handle errors in the privsep_init function, which causes the radvd daemon to run as root and has an unspecified impact. radvd is prone to the follow security vulnerabilities: 1. Multiple local privilege-escalation vulnerability. 2. A local arbitrary file-overwrite vulnerability. 3. Multiple remote denial-of-service vulnerabilities. An attacker can exploit these issues to execute arbitrary code with administrative privileges, overwrite arbitrary files, and cause denial-of-service conditions. The software can replace IPv6 routing for stateless address auto-configuration. The vulnerability is caused by the program not handling the 'privsep_init' function correctly. For more information: SA46203 SA46205 SOLUTION: Apply updated packages via the apt-get package manager. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201111-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: radvd: Multiple vulnerabilities Date: November 20, 2011 Bugs: #385967 ID: 201111-08 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in radvd which could potentially lead to privilege escalation, data loss, or a Denial of Service.

Note: Successful exploitation of this vulnerability requires that the service is running in unicast-only mode. Prior versions may also be affected. SOLUTION: Update to version 1.8.2, which fixes vulnerabilities #1, #3, #4, and #5. Security issue #2 is fixed in the GIT repository.
