How to fix?

Upgrade Ubuntu:14.04 libxslt to version 1.1.28-2ubuntu0.2+esm1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxslt package and not the libxslt package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

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.
