Debian DLA-1088-1 : irssi security update

high Nessus Plugin ID 102926

Synopsis

The remote Debian host is missing a security update.

Description

Irssi has some issues where remote attackers might be able to cause a crash.

CVE-2017-9468

In irssi, when receiving a DCC message without source nick/host, it attempts to dereference a NULL pointer.

CVE-2017-9469

In irssi, when receiving certain incorrectly quoted DCC files, it tries to find the terminating quote one byte before the allocated memory.

For Debian 7 'Wheezy', these problems have been fixed in version 0.8.15-5+deb7u2.

We recommend that you upgrade your irssi packages.

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

Solution

Upgrade the affected irssi, and irssi-dev packages.
