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.
