Hi,
The following vulnerability was published for libxslt.
CVE-2019-13117[0]:
| 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.
The oss-fuzz report and testcases are not public at this moment, but
still filling the bug according to source code view and patch to be
applied. I have no futher details unfortunately.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
