CVE-2019-3881 mitigation

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Bundler prior to 2.1.0 uses a predictable path in /tmp/, created with insecure permissions as a storage     location for gems, if locations under the user's home directory are not available. If Bundler is used in a     scenario where the user does not have a writable home directory, an attacker could place malicious code in     this directory that would be later loaded and executed. (CVE-2019-3881)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:2588 advisory.

    * rubygem-bundler: Insecure permissions on directory in /tmp/ allows for execution of malicious code     (CVE-2019-3881)

    * ruby: NUL injection vulnerability of File.fnmatch and File.fnmatch? (CVE-2019-15845)

    * ruby: Regular expression denial of service vulnerability of WEBrick's Digest authentication     (CVE-2019-16201)

    * ruby: Code injection via command argument of Shell#test / Shell#[] (CVE-2019-16255)

    * rubygem-json: Unsafe object creation vulnerability in JSON (CVE-2020-10663)

    * ruby: BasicSocket#read_nonblock method leads to information disclosure (CVE-2020-10933)

    * ruby: Potential HTTP request smuggling in WEBrick (CVE-2020-25613)

    * ruby: XML round-trip vulnerability in REXML (CVE-2021-28965)

    * ruby: HTTP response splitting in WEBrick (CVE-2019-16254)
