Vulnerability from variot
Buffer overflow in the process_ra function in the router advertisement daemon (radvd) before 1.8.2 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative value in a label_len value. 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 buffer overflow 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.
