GENTOO LINUX SECURITY ANNOUNCEMENT 200303-13
- - ---------------------------------------------------------------------

          PACKAGE : man
          SUMMARY : arbitrary code execution
             DATE : 2003-03-18 18:03 UTC
          EXPLOIT : local
VERSIONS AFFECTED : <1.5l : fixed version>=1.5l
              CVE : CAN-2003-0124

- - ---------------------------------------------------------------------

- From advisory:

"man 1.5l was released today, fixing a bug which results in arbitrary code
execution upon reading a specially formatted man file. The basic problem
is, upon finding a string with a quoting problem, the function my_xsprintf
in util.c will return "unsafe" (rather than returning a string which could
be interpreted by the shell). This return value is passed directly to
system(3) - meaning if there is any program named `unsafe`, it will execute
with the privs of the user."

SOLUTION

It is recommended that all Gentoo Linux users who are running
sys-apps/man upgrade to man-1.5l as follows:

emerge sync
emerge man
emerge clean
