Debian LTS Advisory DLA-3149-1 [email protected]

Package : ruby-nokogiri
Version : 1.10.0+dfsg1-2+deb10u1
CVE ID : CVE-2019-5477 CVE-2020-26247 CVE-2022-24836
Debian Bug : 934802 978967 1009787
Multiple vulnerabilities were discovered in Nokogiri, an
HTML/XML/SAX/Reader parser for the Ruby programming language, leading
to command injection, XML external entity injection (XXE), and
denial-of-service (DoS).
CVE-2019-5477
A command injection vulnerability allows commands to be executed
in a subprocess via Ruby's `Kernel.open` method. Processes are
vulnerable only if the undocumented method
`Nokogiri::CSS::Tokenizer#load_file` is being called with unsafe
user input as the filename. 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.
CVE-2020-26247
XXE vulnerability: XML Schemas parsed by Nokogiri::XML::Schema are
trusted by default, allowing external resources to be accessed
over the network, potentially enabling XXE or SSRF attacks. This
behavior is counter to the security policy followed by Nokogiri
maintainers, which is to treat all input as untrusted by default
whenever possible.
CVE-2022-24836
Nokogiri contains an inefficient regular expression that is
susceptible to excessive backtracking when attempting to detect
encoding in HTML documents.
For Debian 10 buster, these problems have been fixed in version
1.10.0+dfsg1-2+deb10u1.
We recommend that you upgrade your ruby-nokogiri packages.
