Description:


    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).

   - CVE-2015-9019: Properly initialize random generator (bsc#934119).

   - CVE-2015-7995: Vulnerability in function xsltStylePreCompute" in
