Debian DSA-1848-1: Critical Remote Code Execution in ZNC

It was discovered that znc, an IRC proxy, did not properly process
certain DCC requests, allowing attackers to upload arbitrary files.

For the old stable distribution (etch), this problem has been fixed in
version 0.045-3+etch3.

For the stable distribution (lenny), this problem has been fixed in
version 0.058-2+lenny3.

For the unstable distribution (sid), this problem has been fixed in
version 0.074-1.

We recommend that you upgrade your znc package.
