    PACKAGE   : man
    SUMMARY   : Local vulnerability
    DATE      : 2003-04-07 19:22:00

    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.
