The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
irssi: heap buffer overflow due to calculation error in the completion code (CVE-2018-5208)
The buf.pl script before 2.20 in Irssi before 0.8.20 uses weak permissions for the scrollbuffer dump file created between upgrades, which might allow local users to obtain sensitive information from private chat conversations by reading the file. (CVE-2016-7553)
An issue was discovered in Irssi before 1.0.4. When receiving messages with invalid time stamps, Irssi would try to dereference a NULL pointer. (CVE-2017-10965)
Note that Nessus has not tested for these issues but has instead relied on the package manager’s report that the package is installed.
