  script_tag(name:"insight", value:"New kernels are available for Slackware 9.1 and -current. These
have been upgraded to Linux kernel version 2.4.23, which fixes a
bug in the kernel's do_brk() function that could be exploited to
gain root privileges. These updated kernels and modules should be
installed by any sites running a 2.4 kernel earlier than 2.4.23.
Linux 2.0 and 2.2 kernels are not vulnerable.
