# CVE-1999-0849: maxdname bug

Buffer overflow in obscure buffer

```
          CVE: 

                [CVE-1999-0849](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-1999-0849)        

    

        
                  
          Posting date: 

                10 Nov 1999        

    

        
                  
          Program Impacted: 

                [BIND](https://www.isc.org/bind)        

    

        
                  
          Versions affected: 

                4.9.5, 4.9.5 patchlevel 1, 4.9.6, 4.9.7, 4.9.8, 8.1,
```

8.1.1, 8.1.2, 8.2, 8.2 patchlevel 1, 8.2.1, 8.2.2, 8.2.2 patchlevel 1

```
          Severity: 

                Minor        

    

        
                  
          Exploitable: 

                Remotely         

    

  Description: 

        
                The use of sprintf() with data from the network
```

can result in a buffer overflow condition which may result in unexpected behavior. Because of the placement of the buffer which might be overflowed, it is unlikely this bug will result in serious consequences, however the possibility of a remotely triggered server crash cannot be ruled out.

```
  Workarounds: 

        
                None.

    

    

  Active exploits: 

        
                None known at this time.
