Debian Security Advisory DSA 2323-1 (radvd)

CVSS Base Vector:

Technical Details:
Multiple security issues were discovered by Vasiliy Kulikov in radvd, an IPv6 Router Advertisement daemon: CVE-2011-3602 set_interface_var() function doesn't check the interface name, which is chosen by an unprivileged user. This could lead to an arbitrary file overwrite if the attacker has local access, or specific files overwrites otherwise. 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) unconditionally 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). An attacked could flood the daemon with router solicitations in order to fill the input queue, causing a temporary denial of service (processing would be stopped during all the mdelay() calls). 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 Linux Distribution Packages.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
