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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
