Summary: Security update for libmspack

Details: 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).
