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.

Additionally, only a server installation of BrightStor ARCserve Backup for Laptops and Desktops is affected. The client installation is not affected.
