libxslt Type Confusion vulnerability that affects Nokogiri
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. Nokogiri prior to version 1.10.5 used a vulnerable version of libxslt. Nokogiri 1.10.5 updated libxslt to version 1.1.34 to address this and other vulnerabilities in libxslt.
