Buffer overflow in the DoCommand function in jhead before 2.84 might allow context-dependent attackers to cause a denial of service (crash) via (1) a long -cmd argument and (2) unspecified vectors related to "a bunch of potential string overflows."
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.
