* In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings
 could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This
 could allow an attacker to discern whether a byte on the stack contains
 the characters A, a, I, i, or 0, or any other character (CVE-2019-13117).

* In numbers.c in libxslt 1.1.33, a type holding grouping characters of an
 xsl:number instruction was too narrow and an invalid character/length
 combination could be passed to xsltNumberFormatDecimal, leading to a read
 of uninitialized stack data (CVE-2019-13118).

* In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't
 reset under certain circumstances. If the relevant memory area happened to
 be freed and reused in a certain way, a bounds check could fail and memory
 outside a buffer could be written to, or uninitialized data could be
 disclosed (CVE-2019-18197).");
