   An update that fixes 7 vulnerabilities is now available.

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).
