CVE-2009-4020
Published: 4 December 2009
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.
From the Ubuntu Security Team
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.
