Subject: [PATCH] parallels: fix ext_off assertion failure due to overflow
|
|
|
|
cheery-pick from 58607752d173438994d28dea7e2c2587726663e6
|
|
|
|
This error was discovered by fuzzing qemu-img.
|
|
|
|
When ph.ext_off has a sufficiently large value, the operation
|
|
le64_to_cpu(ph.ext_off) << BDRV_SECTOR_BITS in
|
|
parallels_read_format_extension() can cause an overflow in int64_t.
|
|
This overflow triggers the assert(ext_off > 0)
|
|
check in block/parallels-ext.c: parallels_read_format_extension(),
|
|
leading to a crash.
|
|
|
|
This commit adds a check to prevent overflow when shifting ph.ext_off
|
|
by BDRV_SECTOR_BITS, ensuring that the value remains within a valid range.
