CONECTIVA LINUX SECURITY ANNOUNCEMENT

PACKAGE   : man
SUMMARY   : Local vulnerability
DATE      : 2003-04-07 19:22:00
ID        : CLA-2003:620

RELEASES  : 6.0, 7.0, 8

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.
