||||
Subject: [PATCH 3/5] Check segment gaps regardless of heap space.
|
||||
|
||||
Segments are validated in hdr_validate_segments. Gaps in segment keys
|
||||
are detected when collecting offsets. But if an invalid segment is very
|
||||
large, larger than count, it could happen that cryptsetup is unable to
|
||||
allocate enough memory, not giving a clue about what actually is the
|
||||
problem.
|
||||
|
||||
Therefore check for gaps even if not enough memory is available. This
|
||||
gives much more information with debug output enabled.
|
||||
|
||||
Obviously cryptsetup still fails if segments are perfectly fine but not
|
||||
enough RAM available. But at that stage, the user knows that it's the
|
||||
fault of the system, not of an invalid segment.

Subject: [PATCH 4/5] Fix posible buffer overflows in LUKS conversion.
|
||||
|
||||
cipher[31] and cipher_mode[31] buffers were passed to
|
||||
crypt_parse_name_and_mode() routine where sscanf(s, "%31[^-]-%31s",
|
||||
cipher, cipher_mode) was called.
|
||||
|
||||
In corner case it could cause terminating 0 byte written beyond
|
||||
respective arrays.
