CA ARCserve Backup xdr_rwsstring buffer overflow
| ca-arcservebackup-xdrrwsstring-bo (42527) |  High Risk |
Description:
CA ARCserve Backup is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the xdr_rwsstring function. By sending an overly long string to a service that calls the vulnerable function, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
