BNC: Buffer overflow vulnerability

BNC: Buffer overflow vulnerability BNC contains a buffer overflow vulnerability that may lead to Denial of Service and execution of arbitrary code. BNC 2004-11-16 2004-11-16 70674 remote 2.9.1 2.9.1

BNC (BouNCe) is an IRC proxy server.

Leon Juranic discovered that BNC fails to do proper bounds checking when checking server response.

An attacker could exploit this to cause a Denial of Service and potentially execute arbitary code with the permissions of the user running BNC.

There is no known workaround at this time.

All BNC users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/bnc-2.9.1"
