Detail

Multiple vulnerabilities have been discovered in Irssi, a terminal based IRC client. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2017-10965

Brian 'geeknik' Carpenter of Geeknik Labs discovered that Irssi does not properly handle receiving messages with invalid time stamps. A malicious IRC server can take advantage of this flaw to cause Irssi to crash, resulting in a denial of service.

CVE-2017-10966

Brian 'geeknik' Carpenter of Geeknik Labs discovered that Irssi is susceptible to a use-after-free flaw triggered while updating the internal nick list. A malicious IRC server can take advantage of this flaw to cause Irssi to crash, resulting in a denial of service.

CVE-2017-15227

Joseph Bisch discovered that 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. A malicious IRC server can take advantage of this flaw to cause Irssi to crash, resulting in a denial of service.

CVE-2017-15228

Hanno Boeck reported that Irssi does not properly handle installing themes with unterminated colour formatting sequences, leading to a denial of service if a user is tricked into installing a specially crafted theme.

CVE-2017-15721

Joseph Bisch discovered that Irssi does not properly handle incorrectly formatted DCC CTCP messages. A malicious IRC server can take advantage of this flaw to cause Irssi to crash, resulting in a denial of service.

CVE-2017-15722

Joseph Bisch discovered that Irssi does not properly verify Safe channel IDs. A malicious IRC server can take advantage of this flaw to cause Irssi to crash, resulting in a denial of service.

CVE-2017-15723

Joseph Bisch reported that Irssi does not properly handle overlong nicks or targets resulting in a NULL pointer dereference when splitting the message and leading to a denial of service.

For the oldstable distribution (jessie), these problems have been fixed in version 0.8.17-1+deb8u5.

For the stable distribution (stretch), these problems have been fixed in version 1.0.2-1+deb9u3. CVE-2017-10965 and CVE-2017-10966 were already fixed in an earlier point release.

We recommend that you upgrade your irssi packages.
