Vulnerability from variot
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.

Debian Security Advisory DSA-2323-1 security@debian.org http://www.debian.org/security/ Yves-Alexis Perez October 26, 2011 http://www.debian.org/security/faq
Package : radvd Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-3602 CVE-2011-3604 CVE-2011-3605 Debian Bug : 644614
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.
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.

As this call\n is in the main thread, that means all request processing is delayed (for\n a time up to MAX_RA_DELAY_TIME, 500 ms by default). \n Note: upstream and Debian default is to use anycast mode. \n\n\nFor the oldstable distribution (lenny), this problem has been fixed in\nversion 1:1.1-3.1. \n\nFor the stable distribution (squeeze), this problem has been fixed in\nversion 1:1.6-1.1. \n\nFor the testing distribution (wheezy), this problem has been fixed in\nversion 1:1.8-1.2. \n\nFor the unstable distribution (sid), this problem has been fixed in\nversion 1:1.8-1.2. \n\nWe recommend that you upgrade your radvd packages. \n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: http://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\nVersion: GnuPG v1.4.11 (GNU/Linux)\n\niEYEARECAAYFAk6q2QcACgkQXm3vHE4uylqlEQCgpdFwHzpKLF6KHlJs4y/ykeo/\noEYAniJXFaff25pMtXzM6Ovu8zslZm7H\n=VfHu\n-----END PGP SIGNATURE-----\n",
