Title: Computer Associates BrightStor ArcServe Media Server Multiple Remote Buffer Overflow Vulnerabilities
Severity: CRITICAL
Description:
Computer Associates BrightStor ARCserve Backup products provide backup and restore protection for Windows, NetWare, Linux, and UNIX servers as well as Windows, Mac OS X, Linux, UNIX, AS/400, and VMS clients.
The application is prone to multiple remote buffer-overflow vulnerabilities because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer.
The vulnerabilities occur in the SUN RPC service when parsing malformed RPC strings. A remote unauthenticated attacker may exploit this issue to cause memory to become corrupted due to a stack-based buffer overflow.
A remote attacker may exploit these issues to execute arbitrary code with SYSTEM-level privileges. Successful exploits can result in a complete compromise of affected computers. Failed exploit attempts will likely cause denial-of-service conditions.
