ngircd -- format string vulnerability


A No System Group security advisory reports that ngircd is vulnerable to a format string vulnerability in the Log_Resolver() function of log.c, if IDENT support is enabled. This could allow a remote attacker to execute arbitrary code with the permissions of the ngircd daemon, which is root by default.

Note: By default the FreeBSD ngircd port does not enable IDENT support.
