Description: Secunia Research has discovered some vulnerabilities in Symantec Backup Exec for Windows Servers, which can be exploited by malicious people to cause a DoS (Denial of Service). 1) A NULL-pointer dereference error in the Backup Exec Job Engine service (bengine.exe) when handling exceptions can be exploited to crash the service by sending a specially crafted packet to default port 5633/TCP. 2) Two integer overflow errors within the Backup Exec Job Engine service can be exploited to e.g. cause the service to enter an infinite loop and exhaust all available memory or consume large amounts of CPU resource by sending a specially crafted packet to default port 5633/TCP. The vulnerabilities are confirmed in Symantec Backup Exec for Windows Servers version 11d build 11.0.7170 and also affect version 11d build 11.0.6.6235. Solution: Apply hotfixes. Build 11.0.6235: http://support.veritas.com/docs/294241 Build 11.0.7170: http://support.veritas.com/docs/294237 Provided and/or discovered by: JJ Reyes, Secunia Research.
