"The Panda AdminSecure Communications Agent software, which is used for
centralized management of Panda Antivirus, installed on the remote
Windows host contains a flaw in the handling of MESSAGE_FROM_REMOTE
messages.  The software does not properly sanitize inputs, allowing an
attacker to craft a special message that allows traversing outside of a
restricted path.  This may allow a remote attacker to overwrite
arbitrary files and execute remote code with SYSTEM privileges.");
