"Multiple vulnerabilities was found and corrected in busybox :

The decompress function in ncompress allows remote attackers to cause
a denial of service (crash), and possibly execute arbitrary code, via
crafted data that leads to a buffer underflow (CVE-2006-1168).

A missing DHCP option checking / sanitization flaw was reported for
multiple DHCP clients. This flaw may allow DHCP server to trick DHCP
clients to set e.g. system hostname to a specially crafted value
containing shell special characters. Various scripts assume that
hostname is trusted, which may lead to code execution when hostname is
specially crafted (CVE-2011-2716).

Additionally for Mandriva Enterprise Server 5 various problems in the
ka-deploy and uClibc packages was discovered and fixed with this
advisory.

The updated packages have been patched to correct these issues.

Update :

The wrong set of packages was sent out with the MDVSA-2012:129
advisory that lacked the fix for CVE-2006-1168. This advisory provides
the correct packages."
