"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).
