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.
