GEN:SID 1:1941
Message TFTP GET filename overflow attempt
Summary This event is generated by an attempt to exploit a buffer overflow in TFTP file handling routines.
Impact Implementation Dependent.  Several implementations of TFTP are vulnerable to a
buffer overflow when processing long TFTP get requests.  This could allow
arbitrary code execution or result in a Denial of Service condition.
Detailed Information Insufficient bounds checking on requested filenames results in a simple to
exploit buffer overflow condition.  This condition can be exploited by making
a request for an overly long file name.

Affected Systems:
    Cisco IOS 11.1
    Cisco IOS 11.2
    Cisco IOS 11.3
    ATFTP 0.6.0 and 0.6.1.1
Affected Systems  
Attack Scenarios Attackers with access to TFTP can exploit this condition remotely by
