Debian DLA-1089-1 : irssi security update

critical Nessus Plugin ID 102962

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Some Irssi issues were found :

CVE-2017-10965

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-2017-10966

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.

For Debian 7 'Wheezy', these problems have been fixed in version 0.8.15-5+deb7u3.

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.
