Package : znc

Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2009-0759
Debian Bug : 516950
It was discovered that znc, an IRC proxy/bouncer, does not properly
sanitize input contained in configuration change requests to the
webadmin interface. This allows authenticated users to elevate their privileges and indirectly execute arbitrary commands (CVE-2009-0759).
For the old stable distribution (etch), this problem has been fixed in
version 0.045-3+etch2.
For the stable distribution (lenny), this problem has been fixed in
version 0.058-2+lenny1.
For the unstable distribution (sid), this problem has been fixed in
version 0.066-1.
We recommend that you upgrade your znc packages.
