Description

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.
