Impact: A remote attacker can cause a denial of service, execute

arbitrary code, or take privileged action.

Summary: Multiple vulnerabilities exist in BrightStor ARCserve

Backup that can allow a remote attacker to cause a denial of

service, execute arbitrary code, or take privileged action. The

first set of vulnerabilities, CVE-2007-5325, CVE-2007-5326, and

CVE-2007-5327, occur due to insufficient bounds checking by

multiple components. The second vulnerability, CVE-2007-5328,

occurs due to privileged functions being available for use without

proper authorization. The third set of vulnerabilities,

CVE-2007-5329, CVE-2007-5330, CVE-2007-5331, and CVE-2007-5332,

are due to a memory corruption occurring with the processing of

RPC procedure arguments by multiple services. The vulnerabilities

allow an attacker to cause a denial of service, or potentially to

execute arbitrary code.

Note: Updated patches are available. The original patches did not

fully address some issues. Special thanks to Dyon Balding of

Secunia and to Fortinet for reporting issues with the original

patches.
