CA Advisory Date: 2007-10-10 CA Advisory Updated: 2007-12-05
Reported By: Anonymous researcher working with the iDefense VCP (CVE-2007-5325) Dyon Balding of Secunia Research (CVE-2007-5326) Cocoruder of Fortinet Security Research Team (CVE-2007-5327) Tenable Network Security (CVE-2007-5328) Pedram Amini of DV Labs (dvlabs.tippingpoint.com) (CVE-2007-5329) Dyon Balding of Secunia Research (CVE-2007-5330) eEye Digital Security (CVE-2007-5331) shirkdog (CVE-2007-5332)
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.
