EulerOS 2.0 SP2 : irssi (EulerOS-SA-2017-1284)

high Nessus Plugin ID 104903

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 - 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)

 - 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)

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected irssi packages.
