rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.

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

  - rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution     because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.
    (CVE-2021-33477)

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

The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:10222-1 advisory.

  - rxvt 2.6.4 opens a terminal window on :0 if the DISPLAY environment variable is not set, which might allow     local users to hijack X11 connections. NOTE: it was later reported that rxvt-unicode, mrxvt, aterm, multi-     aterm, and wterm are also affected. NOTE: realistic attack scenarios require that the victim enters a     command on the wrong machine. (CVE-2008-1142)

  - rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution     because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.
    (CVE-2021-33477)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202209-07 (Mrxvt: Arbitrary Code Execution)

  - rxvt-unicode 9.22, rxvt 2.7.10, mrxvt 0.5.4, and Eterm 0.9.7 allow (potentially remote) code execution     because of improper handling of certain escape sequences (ESC G Q). A response is terminated by a newline.
    (CVE-2021-33477)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202105-17 (rxvt-unicode: User-assisted execution of arbitrary code)

    It was discovered that rxvt-unicode did not properly handle certain       escape sequences.
  Impact :

    A remote attacker could entice a user to run a program where attacker       controls the output inside a rxvt terminal window, possibly resulting in       execution of arbitrary code with the privileges of the process or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

eterm, an enlightened terminal emulator, allowed (potentially remote) code execution because of improper handling of certain escape sequences (ESC G Q).

For Debian 9 stretch, this problem has been fixed in version 0.9.6-5+deb9u1.

We recommend that you upgrade your eterm packages.
