Description Josh Bressers 2005-03-30 14:17:55 UTC

+++ This bug was initially created as a clone of Bug #152571 +++

Stack-based buffer overflow in shar in GNU sharutils 4.2.1 allows local users to
execute arbitrary code via a long -o command line argument.

To test this:
shar -o `perl -e 'print "A"x2000'`
