• Product: Gentoo Security

[Description Stefan Behte (RETIRED) 2008-11-25 09:19:29 UTC]

CVE-2008-5183 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-5183):
  cupsd in CUPS before 1.3.8 allows local users, and possibly remote
  attackers, to cause a denial of service (daemon crash) by adding a
  large number of RSS Subscriptions, which triggers a NULL pointer
  dereference.  NOTE: this issue can be triggered remotely by
  leveraging CVE-2008-5184.

Name:      CVE-2008-5184
URL:       http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5184
Published: 2008-11-20
Severity:  High
Description:

The web interface (cgi-bin/admin.c) in CUPS before 1.3.8 uses the guest
username when a user is not logged on to the web server, which makes it
easier for remote attackers to bypass intended policy and conduct CSRF
attacks via the (1) add and (2) cancel RSS subscription functions.

I'm going to completely remove all net-print/cups<1.3.8 from the tree now that all arches have stabilized CUPS 1.3(.8). Regarding this bug, CUPS 1.2.x possibly isn't affected by this since it didn't have a RSS option back then.

Everything which is net-print/cups<1.3.8 is now gone, net-print/cups-1.3.8-r2 is stable on all arches and I guess net-print/cups-1.3.9-r1 is going to be stabilized due to security bug #249727.
