perl security update (RHSA-2011-1797)

Original Release Date: January 10, 2012
Last Revised: September 30, 2015
Number: ASA-2012-008
Risk Level: Low
Advisory Version: 7.0
Advisory Status: Final

1. Overview:

Perl is a high-level programming language commonly used for system administration utilities and web programming.

It was found that the "new" constructor of the Digest module used its argument as part of the string expression passed to the eval() function. An attacker could possibly use this flaw to execute arbitrary Perl code with the privileges of a Perl program that uses untrusted input as an argument to the constructor. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-3597 to this issue.

It was found that the Perl CGI module used a hard-coded value for the MIME boundary string in multipart/x-mixed-replace content. A remote attacker could possibly use this flaw to conduct an HTTP response splitting attack via a specially-crafted HTTP request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2761 to this issue.

A CRLF injection flaw was found in the way the Perl CGI module processed a sequence of non-whitespace preceded by newline characters in the header. A remote attacker could use this flaw to conduct an HTTP response splitting attack via a specially-crafted sequence of characters provided to the CGI module. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-4410 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2010-2761
CVE-2010-4410
CVE-2011-3597
Rated a Low as no critical system applications would be affected.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
