Stack-based buffer overflow in the suhosin_encrypt_single_cookie function in the transparent cookie-encryption feature in the Suhosin extension before 0.9.33 for PHP, when suhosin.cookie.encrypt and suhosin.multiheader are enabled, might allow remote attackers to execute arbitrary code via a long string that is used in a Set-Cookie HTTP header.
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.
