Overview
Affected versions of this package are vulnerable to Buffer Overflow due to the fs/quota/quota_tree.c function that does not validate the block number in the quota tree (on disk). Exploiting this vulnerability can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file.
