(switched to plain text) Hi! The following issue was discovered using Kernel Address Sanitizer we're developing (https://code.google.com/p/address-sanitizer/wiki/AddressSanitizerForKernel, https://github.com/google/kasan/blob/kasan/Documentation/kasan.txt) The apparent problem is here (fs/ecryptfs/crypto.c:1866 .. I tested on kernel 3.14, but looks like the issue is still there upstream): static size_t ecryptfs_max_decoded_size(size_t encoded_size) { /* Not exact; conservatively long. Every block of 4 * encoded characters decodes into a block of 3 * decoded characters. This segment of code provides * the caller with the maximum amount of allocated * space that @dst will need to point to in a * subsequent call. */ return ((encoded_size + 1) * 3) / 4; } /** * ecryptfs_decode_from_filename * @dst: If NULL, this function only sets @dst_size and returns. If * non-NULL, this function decodes the encoded octets in @src * into the memory that @dst points to. * @dst_size: Set to the size of the decoded string. * @src: The encoded set of octets to decode. * @src_size: The size of the encoded set of octets to decode. */ static void ecryptfs_decode_from_filename(unsigned char *dst, size_t *dst_size, const unsigned char *src, size_t src_size) { u8 current_bit_offset = 0; size_t src_byte_offset = 0; size_t dst_byte_offset = 0; if (dst == NULL) { (*dst_size) = ecryptfs_max_decoded_size(src_size); goto out; } while (src_byte_offset < src_size) { unsigned char src_byte = filename_rev_map[(int)src[src_byte_offset]]; switch (current_bit_offset) { case 0: dst[dst_byte_offset] = (src_byte << 2); current_bit_offset = 6; break; case 6: dst[dst_byte_offset++] |= (src_byte >> 4); dst[dst_byte_offset] = ((src_byte & 0xF) << 4); current_bit_offset = 4; break; case 4: dst[dst_byte_offset++] |= (src_byte >> 2); dst[dst_byte_offset] = (src_byte << 6); current_bit_offset = 2; break; case 2: dst[dst_byte_offset++] |= (src_byte); dst[dst_byte_offset] = 0; current_bit_offset = 0; break; } src_byte_offset++; } (*dst_size) = dst_byte_offset; out: return; } For src_size multiple of 4 (which I assume is usually the case), the line "dst[dst_byte_offset] = 0;" writes at dst[dst_size] reported in the ecryptfs_max_decoded_size. The caller mallocs exactly dst_size bytes for dst, so the write is outside the allocated space. Depending on allocator, this can be exploited to overwrite the next object's first byte. I didn't exactly understand whether dst should be a 0-terminated string, so we either need to skip writing the trailing zero or allocate 1 more byte.
