Title: CA ARCserve Backup for Laptops and Desktops Server and CA

Desktop Management Suite Multiple Vulnerabilities

CA Advisory Date: 2008-04-03

Reported By: Dyon Balding of Secunia Research

Impact: A remote attacker can execute arbitrary code or cause a

denial of service condition.

Summary: CA ARCserve Backup for Laptops and Desktops Server

contains multiple vulnerabilities that can allow a remote attacker

to execute arbitrary code or cause a denial of service condition.

CA has issued updates to address the vulnerabilities. The first

issue, CVE-2008-1328, occurs due to insufficient bounds checking

on command arguments by the LGServer service. The second issue,

CVE-2008-1329, occurs due to insufficient verification of file

uploads by the NetBackup service. In most cases, an attacker can

potentially gain complete control of an affected installation.

Additionally, only a server installation of BrightStor ARCserve

Backup for Laptops and Desktops is affected. The client

installation is not affected.

Note: the previously published patches for CVE-2007-3216 and

CVE-2007-5005 did not fully address some issues.

Mitigating Factors: Client installations are not affected.

Severity: CA has given these vulnerabilities a maximum risk rating

of High.
