Nokogiri gem, via libxslt, is affected by multiple vulnerabilities
Nokogiri v1.10.5 has been released.
This is a security release. It addresses three CVEs in upstream libxml2,
for which details are below.
If you're using your distro's system libraries, rather than Nokogiri's
vendored libraries, there's no security need to upgrade at this time,
though you may want to check with your distro whether they've patched this
(Canonical has patched Ubuntu packages). Note that libxslt 1.1.34 addresses
these vulnerabilities.
Full details about the security update are available in Github Issue
[#1943] #1943.
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.
Description: 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
Description: In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't
reset under certain circumstances. If the relevant memory area happened to
be freed and reused in a certain way, a bounds check could fail and memory
outside a buffer could be written to, or uninitialized data could be
disclosed.
A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.
This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.
[MRI] Pulled in upstream patch from libxslt that addresses CVE-2019-11068. Full details are available in #1892. Note that this patch is not yet (as of 2019-04-22) in an upstream release of libxslt.
