Strawberry Perl Modules Multiple Vulnerabilities (Windows)

Published: 2012-01-17 11:58:53
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

Successful exploitation will allow attackers to cause an affected application to crash or execute arbitrary perl code.

Affected Versions:
Strawberry Perl PAR module before 1.003 Strawberry Perl Digest module before 1.17 Strawberry Perl Encode module before 2.44 Strawberry Perl PAR::Packer module before 1.012 on winows

Technical Details:
The flaws are due to - an error in par_mktmpdir function in the 'PAR::Packer' and 'PAR' modules creates temporary files in a directory with a predictable name without verifying ownership and permissions of this directory. - the 'Digest->new()' function not properly sanitising input before using it in an 'eval()' call, which can be exploited to inject and execute arbitrary perl code. - off-by-one error in the decode_xs function in Unicode/Unicode.xs in the 'Encode' module. - An error within the 'File::Glob::bsd_glob()' function when handling the GLOB_ALTDIRFUNC flag can be exploited to cause an access violation and potentially execute arbitrary code.

The host is installed with Strawberry Perl and is prone to multiple vulnerabilities.

Upgrade to Strawberry Perl 5.14.2 or later, Upgrade to Strawberry Perl PAR module version 1.003 or later Upgrade to Strawberry Perl Digest module version 1.17 or later Upgrade to Strawberry Perl Encode module version 2.44 or later Upgrade Strawberry Perl PAR::Packer module version 1.012 or later ***** NOTE: Ignore this warning if above mentioned versions of modules are already installed. *****

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".
