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.
