Original Release Date: 2007-01-12 | Last Revised: 2007-02-09


The Computer Associates BrightStor ARCserve Backup Tape Engine RPC service contains a buffer overflow vulnerability. If successfully exploited, this vulnerability may allow a remote attacker to execute arbitrary code.


BrightStor ARCserve Backup is a backup and data retention tool that integrates with other BrightStor Data Availability and BrightStor Storage Management solutions. The Tape Engine features allow BrightStor ARCserve Backup products to use tape drives for storage.

According to a report from Zero Day Initiative, the BrightStor ARCserve Backup Tape Engine RPC service contains a vulnerability that is caused by incorrect handling of malformed RPC requests.
