[curl:bugs] #1179 Buffer Overflow Detection

From: Daniel Stenberg <bagder_at_users.sf.net>
Date: Fri, 18 Jan 2013 22:51:36 +0000

I'm sorry, but that is slightly too old for me to be able to bother. I count more than 2000 commits since that release and we have done more than 350 bug fixes in the almost two years that have passed since that release.

Can you please try a modern version and see if the problem remains?

I'm running typheous (which uses libcurl) on JRuby via the FFI. I got this curious stack trace:
*** buffer overflow detected ***: /usr/bin/java terminated
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(__fortify_fail+0x37)[0x7f8bdd5b3007]
/lib/x86_64-linux-gnu/libc.so.6(+0x107f00)[0x7f8bdd5b1f00]
/lib/x86_64-linux-gnu/libc.so.6(+0x108fbe)[0x7f8bdd5b2fbe]
/usr/lib/x86_64-linux-gnu/libcurl.so.4(curl_multi_fdset+0xeb)[0x7f8b99b9133b]
Any help you can provide would be phenomenal -- I'm having a hard time reliably reproducing (it took hours on a production box with >100 requests a second to trigger this), but I'll keep this ticket up to date with any further information I have.
