CA ARCserve Backup contains multiple vulnerabilities that can allow a remote attacker to cause a denial of service or execute arbitrary code. CA has issued patches to address the vulnerabilities. The first vulnerability, CVE-2008-2241, is due to insufficient path verification by the logging service, caloggerd. An attacker can append data to arbitrary files, which can lead to system compromise. The second vulnerability, CVE-2008-2242, is due to insufficient bounds checking by multiple xdr functions. An attacker can cause an overflow and execute arbitrary code.
