Description:
|
| 6 |
Linux kernel 2.6.x up to 2.6.18 and possibly other versions, when SELinux
|
| 7 |
hooks are enabled, allows local users to cause a denial of service (crash)
|
| 8 |
via a malformed file stream that triggers a NULL pointer dereference in the
|
| 9 |
superblock_doinit function, as demonstrated using an HFS filesystem image.
|
| 10 |
Ubuntu-Description:
|
| 11 |
The hfs file system driver did not properly handle corrupted data
|
| 12 |
structures. By mounting a specially crafted hfs file system, a local
|
| 13 |
attacker could exploit this to crash the kernel. This only affects
|
| 14 |
systems which enable SELinux (Ubuntu disables SELinux by default).
|
| 15 |
Notes:
|
| 16 |
dannf> Though this bug fix applies to 2.4, 2.4 does not include SELinux
|
| 17 |
so it should not be vulnerable to the DoS
