CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Recommendations:
Update your system with the appropriate patches or software upgrades.

Technical Details:
The following Linux Distribution Package is affected: gzip CVE-2006-4334 Unspecified vulnerability in gzip 1.3.5 allows context-dependent attackers to cause a denial of service (crash) via a crafted GZIP (gz) archive, which results in a NULL dereference. CVE-2006-4335 Array index error in the make_table function in unlzh.c in the LZH decompression component in gzip 1.3.5, when running on certain platforms, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted GZIP archive that triggers an out-of-bounds write, aka a 'stack modification vulnerability.' CVE-2006-4336 Buffer underflow in the build_tree function in unpack.c in gzip 1.3.5 allows context-dependent attackers to execute arbitrary code via a crafted leaf count table that causes a write to a negative index. CVE-2006-4337 Buffer overflow in the make_table function in the LHZ component in gzip 1.3.5 allows context-dependent attackers to execute arbitrary code via a crafted decoding table in a GZIP archive. CVE-2006-4338 unlzh.c in the LHZ component in gzip 1.3.5 allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted GZIP archive.

Summary:
The remote host is missing an update to the system as announced in the referenced advisory.

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".
