SuSE-SA:2004:009: Linux Kernel
Medium Nessus Plugin ID 13827
SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SuSE-SA:2004:009 (Linux Kernel).
iDEFENSE Inc. informed us about a buffer overflow in the linux 2.4 kernel code which handles ISO9660 filesystems. The original code is not able to handle very long symlink names.
The vulnerability can be triggered locally by mounting removable media that contains a malformed filesystem or by using the loopback device.
Exploiting this buffer overflow results in kernel-level access to the system.
Another vulnerability allows the retrieval of private informations from JFS filesystems due to the lack of cleaning up (writing zeros) used sectors on the harddrive. This bug needs root privilges to be exploited.
