Stack-based buffer overflow in the hfs_mac2asc function in fs/hfs/trans.c in the Linux kernel 2.6 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via an HFS image with a crafted len field.

Security readout for executives and security teams

CVE-2011-4330 is a Linux kernel HFS filesystem bug. A local user with access to a crafted HFS disk image could crash the system and may be able to run code in kernel context. The risk is concentrated on legacy Linux 2.6 systems that handle HFS media or images. Likely exposure is legacy Linux 2.6 hosts with HFS filesystem support where local users can mount or cause processing of HFS images or media. Servers that never process HFS content have lower practical exposure, but should still verify kernel backports. Treat this as a moderate legacy-platform risk. It is not presented as remotely exploitable or actively exploited, but kernel crashes and possible code execution justify patch verification on any system that may process HFS images. Mitigation focus: Apply a kernel or vendor update containing the HFS name length sanity check.; Check distribution advisories for backported fixes on supported kernels.; Restrict local users from mounting untrusted HFS images where operationally practical..
