> DESCRIPTION
>  The man package, which includes the utilities man, apropos, and
>  whatis is used to read most of the documentation available on a Linux
>  system.
>
>  Jack Lloyd found[1] a local vulnerability in the man utility. Because
>  of a problem with a value returned by the my_xsprintf() function, man
>  could try to execute a program called "unsafe" when reading a manpage
>  file with certain characteristics. If an attacker can put a malicious
>  executable file called "unsafe" in the system PATH and let a user
>  open a specially created manpage, it could run arbitrary commands
>  with the privileges of this user.
>
>
> SOLUTION
>  All users of the "man" package should upgrade.
