Details
Secunia Research notified Symantec of three DoS issues involving erroneous packet handling affecting components of the Symantec Backup Exec for Windows Servers Job Engine. One is a null-pointer dereference issue that crashes the listening service, and two additional issues involving integer overflows that can force the service into an infinite loop resulting in memory exhaustion or high CPU utilization. Successful exploitation requires access to the affected port. In normal installations this would require the attacker to have authorized but non-privileged access to the network on which the targeted server resides to leverage network communications.
A successful attack could result in termination of the targeted service and loss of scheduling services or potentially loss of access to the application until the service is restarted or the targeted activity ceases.
The Common Vulnerabilities and Exposures (CVE) initiative has assigned:
CVE-2007-4346 to the null pointer dereference DoS issue
CVE-2007-4347 to the integer overflow DoS issues
These issues are candidates for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security issues.
SecurityFocus has assigned Bugtraq ID BID 26028 for the null pointer issue and BID 26029 for the integer overflow issues for inclusion in the SecurityFocus vulnerability
