    Description:

    libmspack was updated to fix security issues.

    These security issues were fixed:
    * CVE-2014-9732: The cabd_extract function in cabd.c in libmspack did not
    properly maintain decompression callbacks in certain cases where an
    invalid file follows a valid file, which allowed remote attackers to
    cause a denial of service (NULL pointer dereference and application
    crash) via a crafted CAB archive (bnc#934524).
    * CVE-2015-4467: The chmd_init_decomp function in chmd.c in libmspack did
    not properly validate the reset interval, which allowed remote attackers
    to cause a denial of service (divide-by-zero error and application
    crash) via a crafted CHM file (bnc#934525).
    * CVE-2015-4468: Multiple integer overflows in the search_chunk function
    in chmd.c in libmspack allowed remote attackers to cause a denial of
    service (buffer over-read and application crash) via a crafted CHM file
    (bnc#934526).
    * CVE-2015-4469: The chmd_read_headers function in chmd.c in libmspack did
    not validate name lengths, which allowed remote attackers to cause a
    denial of service (buffer over-read and application crash) via a crafted
    CHM file (bnc#934526).
    * CVE-2015-4470: Off-by-one error in the inflate function in mszipd.c in
    libmspack allowed remote attackers to cause a denial of service (buffer
    over-read and application crash) via a crafted CAB archive (bnc#934527).
    * CVE-2015-4471: Off-by-one error in the lzxd_decompress function in
    lzxd.c in libmspack allowed remote attackers to cause a denial of
    service (buffer under-read and application crash) via a crafted CAB
    archive (bnc#934528).
    * CVE-2015-4472: Off-by-one error in the READ_ENCINT macro in chmd.c in
    libmspack allowed remote attackers to cause a denial of service
    (application crash) or possibly have unspecified other impact via a
    crafted CHM file (bnc#934529).
