Symantec Security Advisory
SYM06-005
17 March 2006
Veritas Backup Exec for Windows Servers: Media Server BENGINE Service Job
log Format String Overflow
Revision History
None
Severity
Low (network/system authorization and specific configuration required)
Remote Access Yes
Local Access No
Authentication Required Yes
Exploit publicly available No
Overview
Backup Exec for Windows Servers Media Server is susceptible to a format
string vulnerability in the job log in BENGINE.exe when job logging is
configured with full details enabled. (Not the default configuration)
An authorized user on the network with a system configured for backup
could potentially host a specifically-formatted file on their system. If
the file name is properly mal-formatted AND the backup is being run with
job logs enabled in Full Details mode, the malicious user could cause a
denial of service on the Media Server or may potentially be able to run
arbitrary code on the system hosting the Media Server.
