TITLE

router advertisement daemon of process_ra Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The process_ra function in the router advertisement daemon (radvd) before 1.8.2 allows remote attackers to cause a denial of service (stack-based buffer over-read and crash) via unspecified vectors. 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. A security vulnerability exists in the 'process_ra' function in radvd 1.8.1 and earlier. ========================================================================== Ubuntu Security Notice USN-1257-1 November 10, 2011 radvd vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS Summary: radvd could be made to crash or overwrite certain files if it received specially crafted network traffic. Software Description: - radvd: Router Advertisement Daemon Details: Vasiliy Kulikov discovered that radvd incorrectly parsed the ND_OPT_DNSSL_INFORMATION option. The default compiler options for affected releases should reduce the vulnerability to a denial of service. This issue only affected Ubuntu 11.04 and 11.10. (CVE-2011-3601) Vasiliy Kulikov discovered that radvd incorrectly filtered interface names when creating certain files. (CVE-2011-3602) Vasiliy Kulikov discovered that radvd incorrectly handled certain lengths. (CVE-2011-3604) Vasiliy Kulikov discovered that radvd incorrectly handled delays when used in unicast mode, which is not the default in Ubuntu. If used in unicast mode, a remote attacker could cause radvd outages, resulting in a denial of service. (CVE-2011-3605) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: radvd 1:1.8-1ubuntu0.1 Ubuntu 11.04: radvd 1:1.7-1ubuntu0.1 Ubuntu 10.10: radvd 1:1.6-1ubuntu0.1 Ubuntu 10.04 LTS: radvd 1:1.3-1.1ubuntu0.1 In general, a standard system update will make all the necessary changes.

CVE-2011-3604 process_ra() function lacks multiple buffer length checks which could lead to memory reads outside the stack, causing a crash of the daemon. CVE-2011-3605 process_rs() function calls mdelay() (a function to wait for a defined time) unconditionnally when running in unicast-only mode. As this call is in the main thread, that means all request processing is delayed (for a time up to MAX_RA_DELAY_TIME, 500 ms by default). Note: upstream and Debian default is to use anycast mode. For the oldstable distribution (lenny), this problem has been fixed in version 1:1.1-3.1. For the stable distribution (squeeze), this problem has been fixed in version 1:1.6-1.1. For the testing distribution (wheezy), this problem has been fixed in version 1:1.8-1.2. For the unstable distribution (sid), this problem has been fixed in version 1:1.8-1.2. We recommend that you upgrade your radvd packages.
