CVE-2019-13117
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.
Does this matter?
Lower severity and a low EPSS score (6.46%). Track it; it rarely justifies an emergency change on its own.
Description
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.
