>7. Problem description:
>
>A buffer overflow existed in libtermcap's tgetent() function,
>which could cause the user to execute arbitrary code if they
>were able to supply their own termcap file.
>
>Under Red Hat Linux 5.2 and 4.2, this could lead to local users
>gaining root privileges, as xterm (as well as other possibly
>setuid programs) are linked against libtermcap. Under Red Hat
>Linux 6.0, xterm is not setuid root.
>
>Thanks go to Kevin Vajk and the Linux Security Audit team for
>noting and providing a fix for this vulnerability.

>8. Solution:
>
>For each RPM for your particular architecture, run:
>
>rpm -Uvh <filename>
>
>where filename is the name of the RPM.

>MD5 sum Package Name
