    Date 10 Mar 2009

    Posted By LinuxSecurity Advisories
    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).

    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.
