The upstream changes introduced a regression when using irssi with SSL and an IRC proxy. This update fixes the problem. We apologize for the inconvenience. It was discovered that irssi did not perform certificate host validation when using SSL connections. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2010-1155) Aurelien Delaitre discovered that irssi could be made to dereference a NULL pointer when a user left the channel. A remote attacker could cause a denial of service via application crash. (CVE-2010-1156) This update also adds SSLv3 and TLSv1 support, while disabling the old, insecure SSLv2 protocol. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-06-01 modified 2020-06-02 plugin id 45589 published 2010-04-21 reporter Ubuntu Security Notice (C) 2010-2019 Canonical, Inc. / NASL script (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/45589 title Ubuntu 8.04 LTS / 8.10 / 9.04 / 9.10 : irssi regression (USN-929-2) NASL family SuSE Local Security Checks NASL id SUSE_11_2_IRSSI-100427.NASL description irssi did not check the identity information of a remote hosts last seen 2020-06-01 modified 2020-06-02 plugin id 46190 published 2010-04-30 reporter This script is Copyright (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/46190 title openSUSE Security Update : irssi (openSUSE-SU-2010:0183-1) NASL family SuSE Local Security Checks NASL id SUSE_11_0_IRSSI-100427.NASL description irssi did not check the identity information of a remote hosts last seen 2020-06-01 modified 2020-06-02 plugin id 46186 published 2010-04-30 reporter This script is Copyright (C) 2010-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/46186 title openSUSE Security Update : irssi (openSUSE-SU-2010:0183-1) NASL family Mandriva Local Security Checks NASL id MANDRIVA_MDVSA-2010-079.NASL description Multiple vulnerabilities has been found and corrected in irssi : Irssi before 0.8.15, when SSL is used, does not verify that the server hostname matches a domain name in the subject last seen 2020-06-01 modified 2020-06-02 plugin id 48180 published 2010-07-30 reporter This script is Copyright (C) 2010-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/48180 title Mandriva Linux Security Advisory : irssi (MDVSA-2010:079) NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_3B7967F149E811DF83FB0015587E2CC1.NASL description Two vulnerabilities have found in irssi.
