Perl is a popular scripting language for a multitude of tasks, including writing system administration tools, web applications and a myriad of "glue" programs to tie separate applications and/or data sources together.
A flaw in how environment variables were handled was found in the setuid wrapper for Perl (sperl). A local user could possibly cause the sperl wrapper to create arbitrary files and/or append debug information to the end of existing files based on setting an environment variable at runtime. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0155 to this issue.
This issue was originally fixed in RHSA-2005:103 and updated Perl packages were issued accordingly. However, updates to the Perl packages made by RHSA-2006:674 did not contain the fixes applied from RHSA-2005:103, causing the issue fixed in RHSA-2005:103 to surface again. Accordingly, a separate CVE number has been assigned to document the reversion of the patches to the Perl packages from RHSA-2005:103. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-3813 to the issue.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Messaging Storage Server | MSS 3.0 | Low | Upgrade to MSS 3.1 or later. |
Recommended Actions:
For all system products which use vulnerable
versions of perl, Avaya recommends that customers restrict local and network
access to the server. This restriction should be enforced through the use of
physical security, firewalls, ACLs, VPNs, and other generally-accepted
networking practices until such time as an upgrade can be installed.
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 vendors guidance.
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Interactive Response(IR) | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IR application. The IR application does not require the software described in this advisory. |
| CVLAN | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the CVLAN application. The CVLAN application does not require the software described in this advisory. |
| Avaya Integrated Management Suite(IMS) | All | None | Depending on the Operating System provided by customers, the affected packages may be installed on the underlying Operating System supporting the IMS application. The IMS application does not require the software described in this advisory. |
Recommended Actions:
Avaya recommends that customers follow
recommended actions supplied by the Operating System vendor (e.g. RedHat
Linux) or remove the affected packages.
