  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nftruncate: pass a signed offset\nThe old ftruncate() syscall, using the 32-bit off_t misses a sign\nextension when called in compat mode on 64-bit architectures.  As a\nresult, passing a negative length accidentally succeeds in truncating\nto file size between 2GiB and 4GiB.\nChanging the type of the compat syscall to the signed compat_off_t\nchanges the behavior so it instead returns -EINVAL.\nThe native entry point, the truncate() syscall and the corresponding\nloff_t based variants are all correct already and do not suffer\nfrom this mistake.", "An unexpected file truncate flaw was found when opening files with specific parameters in the Linux kernel's file-system. This vulnerability allows a local user to corrupt specific files when having access to these files." ],
