A large number of attacks on SuSE and Sun servers have been reported. Most of these attacks have been successful, and were used to install sniffers and IRC bots causing additional compromising of other systems that were located on the same network.
The attacks took place between May 1st and May 3rd. |

Several Linux SuSE machines (and also some Sun machines) within the domain tu-bs.de have been massively hacked between May 1st to May 3rd.
The attacks exploited buffer overflow vulnerability in the local mountd to gain root access. Then linsniffer (TCP packet sniffer) and eggdrop (IRC bot) have been installed. The following is a sample of the kernel messages during the attack:
May 2 06:16:03 rudolph mountd[103]: Unauthorized access by NFS client 194.167.74.19.
May 2 06:16:04 rudolph mountd[103]: [truncated] Blocked attempt of 194.167.74.19 to mount

This vulnerability has been reported to CERT (see http://www.cert.org/advisories/CA-98.12.mountd.html).
The hackers successfully penetrated SuSE 6.1 machines. No fix is currently available for this version, leaving most SuSE 6.1 machines still vulnerable.
