Alpine: multiple irssi packages: security update to 1.0.5-r0

high Tenable Cloud Security Plugin ID 405013

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Irssi before 1.0.5, while waiting for the channel synchronisation, may incorrectly fail to remove
destroyed channels from the query list, resulting in use-after-free conditions when updating the state
later on. (CVE-2017-15227)

- Irssi before 1.0.5, when installing themes with unterminated colour formatting sequences, may access data
beyond the end of the string. (CVE-2017-15228)

- In Irssi before 1.0.5, certain incorrectly formatted DCC CTCP messages could cause a NULL pointer
dereference. This is a separate, but similar, issue relative to CVE-2017-9468. (CVE-2017-15721)

- In certain cases, Irssi before 1.0.5 may fail to verify that a Safe channel ID is long enough, causing
reads beyond the end of the string. (CVE-2017-15722)

- In Irssi before 1.0.5, overlong nicks or targets may result in a NULL pointer dereference while splitting
the message. (CVE-2017-15723)
