Published: 2009-08-17 12:35:19
CVE Author: NIST National Vulnerability Database

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

Detection Type:
Executable Unreliable

Impact:
Successful exploitation will allow attackers to execute arbitrary code in the context of an affected application, and can cause Denial of Service.

Affected Versions:
Apache APR version 0.9.x and 1.3.x before 1.3.8 Apache APR-Utils version 0.9.x and 1.3.x before 1.3.9

Technical Details:
The following issues exist: - An error exists when vectors trigger crafted calls to the allocator_alloc or apr_palloc function in memory/unix/apr_pools.c in APR. - An error in apr_rmm_malloc, apr_rmm_calloc or apr_rmm_realloc function in misc/apr_rmm.c is caused while aligning relocatable memory blocks in APR-util.

Summary:
The host is installed with Apache APR and APR-Util and is prone to multiple Integer Overflow vulnerabilities.

Solution Type:
Vendor Patch

Recommendations:
Upgrade to Apache APR version 1.3.8 or APR-util version 1.3.9 or apply the patches for Apache APR-Utils 0.9.x or Apache APR version 0.9.x. Please see the references for more information. ***** NOTE: Ignore this warning if above mentioned patch is already applied. *****

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".
