In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ntfs: detect mapping-pairs LCN accumulator overflow<\/p>\n
The NTFS mapping-pairs parser accumulates relative LCN deltas in a
\nsigned integer. A corrupted attribute can drive that addition past
\nthe representable range.<\/p>\n
One corrupt runlist shape sets the accumulated LCN to S64_MAX and
\nthen adds a delta of 1 in the next mapping-pairs entry.<\/p>\n
Signed overflow is undefined and can turn an invalid runlist into a
\ndifferent set of physical clusters.<\/p>\n
Check the LCN addition for overflow before storing the next run.<\/p>\n","protected":false},"excerpt":{"rendered":"
