It was discovered that there was an issue in the irssi IRC client where certain nick names could result in out-of-bounds access when printing theme strings.
For Debian 7 ‘Wheezy’, this issue has been fixed in irssi version 0.8.15-5+deb7u6. It was incorrectly missing from the upload of 0.8.15-5+deb7u5 announced as part of DLA-1289-1. Thanks to Ben Hutchings and Matus Uhlhar.
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.
