Description:
 Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32
 allows remote attackers to have an unspecified impact via a crafted
 Hierarchical File System (HFS) filesystem, related to the hfs_readdir
 function in fs/hfs/dir.c.
Ubuntu-Description:
 Amerigo Wang discovered that HFS filesystem did not correctly validate
 disk structures.  If a user were tricked into mounting a specially crafted
 HFS filesystem, a remote attacker could crash the system or gain root
 privileges.
