According to the versions of the irssi package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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)

  - An issue was discovered in Irssi before 1.0.4. While     updating the internal nick list, Irssi could     incorrectly use the GHashTable interface and free the     nick while updating it. This would then result in     use-after-free conditions on each access of the hash     table.(CVE-2017-10966)

  - In Irssi before 1.0.3, when receiving a DCC message     without source nick/host, it attempts to dereference a     NULL pointer. Thus, remote IRC servers can cause a     crash.(CVE-2017-9468)

  - In Irssi before 1.0.3, when receiving certain     incorrectly quoted DCC files, it tries to find the     terminating quote one byte before the allocated memory.
    Thus, remote attackers might be able to cause a     crash.(CVE-2017-9469)

  - In Irssi before 1.0.6, a calculation error in the     completion code could cause a heap buffer overflow when     completing certain strings.(CVE-2018-5208)

  - Irssi before 0.8.21 allows remote attackers to cause a     denial of service (out-of-bounds read and crash) via a     string containing a formatting sequence (%[) without a     closing bracket (]).(CVE-2017-5356)

  - The nickcmp function in Irssi before 0.8.21 allows     remote attackers to cause a denial of service (NULL     pointer dereference and crash) via a message without a     nick.(CVE-2017-5193)

  - Use-after-free vulnerability in Irssi before 0.8.21     allows remote attackers to cause a denial of service     (crash) via an invalid nick message.(CVE-2017-5194)

  - When the channel topic is set without specifying a     sender, Irssi before 1.0.6 may dereference a NULL     pointer.(CVE-2018-5206)

  - When using an incomplete variable argument, Irssi     before 1.0.6 may access data beyond the end of the     string.(CVE-2018-5207)

  - When using incomplete escape codes, Irssi before 1.0.6     may access data beyond the end of the     string.(CVE-2018-5205)

This update for irssi to version 1.0.6 fixes several issues that may affect the stability of irssi :

  - CVE-2018-5205: Data access beyond the end of the string     when using incomplete escape codes

  - CVE-2018-5206: NULL pointer dereference when the channel     topic is set without specifying a sender

  - CVE-2018-5207: When using an incomplete variable     argument, Irssi may access data beyond the end of the     string

  - CVE-2018-5208: Heap buffer overflow when completing     certain strings

Multiple vulnerabilities have been discovered in Irssi, a terminal-based IRC client which can result in denial of service.
