"This update for libxslt fixes the following security 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 preproc.c could cause a type
    confusion leading to DoS. (bsc#952474) This update was
    imported from the SUSE:SLE-12:Update update project."
