Previously Common Vulnerabilities and Exposures assigned an identifier of CVE-2009-4020 to the following vulnerability:

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.

Statement:

This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG, as those versions do not have CONFIG_HFSPLUS_FS option enabled.

The Red Hat Security Response Team has rated this issue as having low security impact. A future kernel updates in Red Hat Enterprise Linux 5 may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.
