- 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)");
