curl_read_cb is callback function for libcurl when data arrives. The data size passed in here is not guaranteed to be within the range of request we submitted, so we may overflow the guest IO buffer.

Other variables (e.g. sectors_per_block) are calculated using these variables, and if not range-checked illegal values could be obtained causing infinite loops and other potential issues when calculating BAT entries. The 1.00 VHDX spec requires BlockSize to be min 1MB, max 256MB. LogicalSectorSize is required to be either 512 or 4096 bytes.

2014-04-01vdi: add bounds checks for blocks_in_image and disk_size header fields ↵Jeff Cody1-4/+33
(CVE-2014-0144) The maximum blocks_in_image is 0xffffffff / 4, which also limits the maximum disk_size for a VDI image to 1024TB. Note that this is the maximum size that QEMU will currently support with this driver, not necessarily the maximum size allowed by the image format.

This adds checks to make sure that max_table_entries and block_size are in sane ranges. Memory is allocated based on max_table_entries, and block_size is used to calculate indices into that allocated memory, so if these values are incorrect that can lead to potential unbounded memory allocation, or invalid memory accesses. Also, the allocation of the pagetable is changed from g_malloc0() to qemu_blockalign().

2014-04-01bochs: Unify header structs and make them QEMU_PACKEDKevin Wolf1-42/+25
This is an on-disk structure, so offsets must be accurate. Before this patch, sizeof(bochs) != sizeof(header_v1), which makes the memcpy() between both invalid. We're lucky enough that the destination buffer happened to be the larger one, and the memcpy size to be taken from the smaller one, so we didn't get a buffer overflow in practice. This patch unifies the both structures, eliminating the need to do a memcpy in the first place. The common fields are extracted to the top level of the struct and the actually differing part gets a union of the two versions.

2014-04-01block/cloop: fix offsets[] size off-by-oneStefan Hajnoczi1-7/+5
cloop stores the number of compressed blocks in the n_blocks header field. The file actually contains n_blocks + 1 offsets, where the extra offset is the end-of-file offset. The following line in cloop_read_block() results in an out-of-bounds offsets[] access: uint32_t bytes = s->offsets[block_num + 1] - s->offsets[block_num]; This patch allocates and loads the extra offset so that cloop_read_block() works correctly when the last block is accessed. Notice that we must free s->offsets[] unconditionally now since there is always an end-of-file offset.

2014-04-01block/cloop: prevent offsets_size integer overflow (CVE-2014-0143)Stefan Hajnoczi1-0/+7
The following integer overflow in offsets_size can lead to out-of-bounds memory stores when n_blocks has a huge value: uint32_t n_blocks, offsets_size; [...] ret = bdrv_pread(bs->file, 128 + 4, &s->n_blocks, 4); [...] s->n_blocks = be32_to_cpu(s->n_blocks); /* read offsets */ offsets_size = s->n_blocks * sizeof(uint64_t); s->offsets = g_malloc(offsets_size); [...] for(i=0;i<s->n_blocks;i++) { s->offsets[i] = be64_to_cpu(s->offsets[i]); offsets_size can be smaller than n_blocks due to integer overflow. Therefore s->offsets[] is too small when the for loop byteswaps offsets. This patch refuses to open files if offsets_size would overflow. Note that changing the type of offsets_size is not a fix since 32-bit hosts still only have 32-bit size_t.

2014-03-19qcow2: Fix fail path in realloc_refcount_block()Max Reitz1-16/+18
If qcow2_alloc_clusters() fails, new_offset and ret will both be negative after the fail label, thus passing the first if condition and subsequently resulting in a call of qcow2_free_clusters() with an invalid (negative) offset parameter. Fix this by introducing a new label "fail_free_cluster" which is only invoked if new_offset is indeed pointing to a newly allocated cluster that should be cleaned up by freeing it. While we're at it, clean up the whole fail path. qcow2_cache_put() should (and actually can) never fail, hence the return value can safely be ignored (aside from asserting that it indeed did not fail). Furthermore, there is no reason to give QCOW2_DISCARD_ALWAYS to qcow2_free_clusters(), a mere QCOW2_DISCARD_OTHER will suffice. Ultimately, rename the "fail" label to "done", as it is invoked both on failure and success.

It shouldn't do this when another qemu instance is still actively working on this image file.

Reads from (meta)data after the old EOF return only zeroes, causing image corruption.
