Red Hat Bugzilla – Bug 8530
Little buffer overflow
Last modified: 2008-05-01 11:37:53 EDT
Lately, I found out that pine 4.10, which ships with Red Hat's
latest distributions, has a buggy pico. We can easily overflow
pico while it is evaluating command-line arguments, thus forcing
it to leave a coredump.
Although I haven't checked out pine's source, yet, I suspect
there's a badly written strcpy() out there.
Just start pico and feed it with a 101+ character long filename. It should
immeadiately die. I informed the UW PINE maintainers, and the latest
versions are already fixed. Therefore, 4.20 is not affected.
BTW, joe is also vulnerable.

We've updated to 4.21 a while ago - that should fix it.
