Description Kees de Jong 2017-11-04 20:03:04 UTC

Description of problem:
Current release (irssi-1.0.4-1.fc26.x86_64) is vulnerable, a fix has been out for 2 weeks: https://github.com/irssi/irssi/releases/tag/1.0.5


(a) When installing themes with unterminated colour formatting
    sequences, Irssi may access data beyond the end of the
    string. (CWE-126) Found by Hanno Böck.

    CVE-2017-15228 was assigned to this issue.

(b) While waiting for the channel synchronisation, Irssi may
    incorrectly fail to remove destroyed channels from the query list,
    resulting in use after free conditions when updating the state
    later on. Found by Joseph Bisch. (CWE-416 caused by CWE-672)

    CVE-2017-15227 was assigned to this issue.

(c) Certain incorrectly formatted DCC CTCP messages could cause NULL
    pointer dereference. Found by Joseph Bisch. This is a separate,
    but similar issue to CVE-2017-9468. (CWE-690)

    CVE-2017-15721 was assigned to this issue.

(d) Overlong nicks or targets may result in a NULL pointer dereference
    while splitting the message. Found by Joseph Bisch. (CWE-690)

    CVE-2017-15723 was assigned to this issue.

(e) In certain cases Irssi may fail to verify that a Safe channel ID
    is long enough, causing reads beyond the end of the string. Found
    by Joseph Bisch. (CWE-126)
    CVE-2017-15722 was assigned to this issue.

Comment 1 Jaroslav Škarvada 2017-12-18 14:42:35 UTC

It has been fixed since October 23 in Rawhide. Please set the version field correctly next time. I am also going to rebase it in f26 and f27.
