Debian Security Advisory DSA-1735-1 security@debian.org

Package : znc
Vulnerability : missing input sanitization
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.
