Comment 1 Jan Lieskovsky 2013-03-29 11:29:14 UTC

This issue affects the versions of the ngircd package, as shipped with Fedora release of 18 and Fedora EPEL-6. Please schedule an update.

Comment 2 Jan Lieskovsky 2013-03-29 11:30:07 UTC

Created ngircd tracking bugs for this issue

Affects: fedora-18 [bug 929170]
Affects: epel-6 [bug 929171]

Comment 3 Jan Lieskovsky 2013-03-29 11:34:23 UTC

Based on upstream ngIRCd 20.2 notification:
  http://arthur.barton.de/pipermail/ngircd-ml/2013-February/000623.html

this issue is reported to affect only ngIRCd versions of "ngIRCd 20 and 20.1 (Please note that all releases before 20 are NOT affected by the bug mentioned
above)".

therefore I didn't create a child bug for Fedora-17 and EPEL-5. But if you are of the opinion that upstream patch:
  https://arthur.barton.de/cgi-bin/gitweb.cgi?p=ngircd.git;a=commitdiff;h=0e63fb3fa7ac4ca048e8c2b648d2be3fd0572311;hp=3e723318961b452c851eda2bec2a322fc249bfce

after backport should be applied against Fedora-17 and EPEL-5 versions too, and would need child bugs for those versions, let me know and I will create them.

Thank you, Jan.
