This update for libxslt fixes the following issues:

• CVE-2017-5029: The xsltAddTextString function in transform.c lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page (bsc#1035905).

• CVE-2016-4738: Fix heap overread in xsltFormatNumberConversion: An empty decimal-separator could cause a heap overread. This can be exploited to leak a couple of bytes after the buffer that holds the pattern string (bsc#1005591).
