Security Notice for CA ARCserve Backup
caloggerd and xdr functions

Issued: May 19, 2008

CA's customer support is alerting customers to security risks associated with CA ARCserve Backup. Multiple vulnerabilities exist 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.

Note: These issues only affect the server installation.
