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 applicationβs self-reported version number.
